The mystery of death, its suffering and its cold finality, have preoccupied humans for probably longer than humanity itself. The possibility of continued existence through successive rebirths is also an ancient belief.
One minute a person, often a loved one or maybe a patient in your hospital, a passenger in a car nearby, or a soldier in the Humvee ahead of you, is there and the next moment he or she is gone. It's an eerie and startling experience.
Once in college as I was studying in my curtained off garage study and meditation room, an accident took place late at night. I heard a scream and then sudden silence. A car had struck a motorcycle outside my house and the cyclist was lying dead on the street. There was no one else around, apart from the driver of the car. The night was silent and this poor soul had been swallowed up by it.
Another time deep in the woods I watched an inexperienced canoeist paddle out to help some boys whose canoe had tipped over as they steered away from the deadly rapids and falls towards the portgage trail. But as we, and his wife and children watched in astonishment from shore, the self-appointed rescuer, not in control of his own canoe, literally paddled out and right over the falls -- never to be found. The look on his face only yards away from us as he realized in horror his slow-motion, surreal mistake will never be forgotten. His wife's tortured screams and shock still ring in my ears.
The lights go out and the building is untenanted. What a mystery.
We, identified as we are with our bodies, cannot help but feel a sense of loss and grief in the face of death's silence. Paramhansa Yogananda, the renowned master of yoga (life force) and author of the classic story "Autobiography of a Yogi," described the death experience on many occasions and in some of his writings.
Meditation as practiced by a master is, quite literally, the conscious reeanctment of the death experience but without its finality. Thus such a one is competent to speak of it. We also have descriptions from those who have had the near-death experience.
Death resembles our nightly sleep experience in some ways. Just as when we fall deeper into sleep, the body and its senses become insensate as our life vitality withdraws from the body. But at death with the last breath our life force makes its final exhalation journey to the base of the astral spine before beginning its return journey and ascension up the central spine (sushumna). In this ascension our life force is squeezed and compressed and many people feel anxious or fearful. In addition, at this moment our physical body has ceased breathing. Much of the struggle against the cessation of the breath cycle has already taken place earlier such that at the final exhalation there is not necessarily further struggle. The life force by this moment is so internalized that awareness of the body and breath has vanished.
As our life force (astral body) squeezes into the sushumna and begins to rise in its tunnel, we are entering another birth canal and often feel a similar level of stress and anxiety as we observe in a new-born during its progress through the mother's birth canal. The near-death report of going through a long dark tunnel is in fact a description of this phase. The light at the end of that tunnel is the light of the astral regions into which we are about to enter: being re-born onto the astral plane!
The light welcome us and comforts us as our life force exits through the region near the medulla oblongata at the base of the brain (the negative pole of the sixth chakra). The expansion of our astral body upon its exit is like the diver, out of breath, breaking the surface and taking in much needed air. It is a relief to come out of the tunnel!
As the physical mouth takes in food and water, the "mouth of God" at the medulla (the astral body) takes in life force to sustain the physical body. Just as food and water cannot revive a dead person or as water into a battery cannot revive a dead battery, so too does the physical body rely most essentially on life force (known as prana, chi, cosmic energy, etc.). Thus there are corroborated stories of saints who, to demonstrate this truth, are given the grace to live without food or water--for decades. Therese Neumann in Bavaria in the 20th century was one such saint who was repeatedly examined by medical doctors.
Still, the death experience can be anxiety filled and dreaded, especially to those unprepared for it especially in how they have lived. The more we live for bodily comfort and pleasure and for ego-affirmation the more we feel deprivation and fear for losing control and awareness in the body. The more a person lives on a higher mental, emotional, or spiritual plane the less attached to the body and the more likely one is to be calm and peaceful. Death, it has been well said, is the final exam of how we have lived our life.
It is not always so, of course: cases of instant death; prolonged unconsciousness and so on. But it is often the case.
One of the great mysteries is to what extent do we remain conscious and to what degree is the after-death experience a pleasant or unpleasant one. This is as varied as the cosciousness of humans and cannot be but merely generalized.
Death deprives us of the body. To the degree one cannot exist without sensory stimuli, one feels the deprivation presumably as loss, as loneliness, and as suffering. This can be temporary as part of the death process or it can remain: depending upon the intensity of one's identification with the physical body. We can call this sensory deprivation.
Like a fish out of water or a climber reaching great heights, our experience depends largely on the degree to which, during life, we have experienced the "oxygen-less" (breathless) altitudes of superconsciousness. Deep and (near) breathless states of meditation are achievable by anyone willing to make the effort to meditate using proven methods of meditation.
Those of great artistic sensitivity or scientific, inventive, philosophical, or other high states of mental concentation and ability also may remain conscious in the astral state. Those who possess great compassion rendering humanitarian service and engaged in prolonged hours of self-forgetfulness which lift them beyond bodily identification also experience more readily the airless astral regions in comfort and joy.
But most people who receive the comfort of the Light upon exiting the body cannot, for very long, sustain conscious awareness in these higher altitudes of the astral region without falling back asleep for having been deprived of the vehicle of their physical body.
Before doing so, however, first two things are commonly experienced. One is some degree of comfort: whether described as being welcomed by loved ones, previously departed, or by God, angels, or one of the masters. Relief at having survived what they thought was death is no small part of the joy one feels upon entering the astral realm.
Another is the reading of the book of life. In some timeless moment we see, if but in an instant, a re-run of the life just lived. We may discover to our surprise important scenes we hadn't noticed. But we receive as if from the soul's even but temporary awakening a God's eye view of our life.
This is the judgment so often referred to. It is Self-judgment however even if we, having failed to become acquainted with our Higher Self, experience that Self as "Other" and therfore as a Judge.
But as I say, those who cannot but briefly sustain this high altitude of superconsciousness then fall asleep. Old age can bring suffering of all levels and many in fact desire and need, as we do nightly, their earned repose. Those who can remain awake on that high plane do so. For those I refer to the chapter, in Autobiography of a Yogi, entitled "The Resurrection of Sri Yukteswar." In this chapter he describes the astral and causal regions.
A sideline to the astral realms relates to the effect of shedding the confinement of the physical body. Swami Kriyananda, a direct disciple and founder of Ananda, describes how, uncorked form the physical form, our feelings and states of consciousness are greatly intensified on the astral plane. If we have a calm, peaceful and harmonious consciousness we expand joyfull into that. If we have lived with lust and desire, anger and resentment, we expand into the seemingly endless hell of such states which, deprived of a physical body, can find no outlet, no fulfillment.
Just as near dawn we begin to stir from our deep nightly slumber, so too souls begin to stir when the time of their rest is soon to be over. And, like we at night, they too may have intermitten dreams of loved ones or scenes from their prior life during this astral sleep. But near dawn, we stir, sometimes fitfully, for the next life's lessons and tasks (and desires) call to us.
Yogananda taught that when a couple unite sexually, and sperm and ovum unite (these are not necessarily simultaneous, I know), a flash of light occurs on the astral realm. I once read in National Georgraphic that when the sperm penetrates the husk of the ovum, an electrical charge goes off! At that moment, those souls whose time it is to return all rush, competitively, to enter that womb. But only those souls who have some relative vibrational harmony with the consciousness of that couple (we could say karmic resonance, too) are attracted to this light. Thus begins, as Yogananda put it, our first race for survival: a portent to the endless contention and effort required to live in a physical body.
What then is reincarnation? Reincarnation posits that individual souls return to new bodies repeatedly over vast epochs of time as the consequence of past actions (which include past desires).
It is said that this process is necessary because our immortal and changeless soul has misunderstood its true nature by identification with the passing drama of its many physical forms and the cumulative effect of the likes and dislikes, actions and reactions which arise from it. These many lives offer the soul the opportunity to learn and grow towards Self-realization (or to postone those lessons). Self-realization is the realization that we are the soul and not the body or personality. This soul, or Atman, is destined to become one with the Creator but this destiny must be obtained by its willing choice, not by compulsion.
Surveys show that the majority of humans on this planet subscribe to or accept as plausible the idea of mutliple births.
Yet the fact of death is undeniably final as it relates to our body and the personality which had inhabited it. Countless, however, are those who claim they have had some post-death contact with their loved one. Many are the stories of near-death experiences attesting to our disincarnate and deathless reality.
What aspect of our Self continues and what aspect is lost? There are remarkable and many stories of children with clear and convincing memories of their past life. (The relatively recent story, "Soul Survivor," is worth reading.)
Since we can safely say that most humans DO NOT remember their past lives (except perhaps in flitting glimpses or oddly familiar feelings about others, places, or objects....but just occasionally), something is lost, to us at least. Of course isn't memory loss in THIS lifetime a serious problem? Why should we fret, then, over loss over memory due to the intensity of the after death sojourn in astral sleep. Interestingly, it seems that dying takes place early as year after year our memories fade, as if in anticipation!
If the power goes out when your are sitting at your computer in the middle of multiple programs, your work is at least partially lost. If a program crashes and cannot be restarted, the data remains on the hard drive but, without the program, cannot typically be accessed. When you delete a file, only the index of how to find that file is erased. The file itself remains on the hard drive. Deleting that index is somewhat akin to the loss of the physical body. But the matrix of the astral body retains the data for later use and recovery. The conscious mind may have no access to it, however.
Each life is indeed unique: as to time, space, circumstances, events, and the resulting combination of attitudes, habits, and insights the grow up around this unique time-space experience. But when we die, those external circumstances whose influence is undeniable disappear and with them those merely superficial incidentals of our personality which depended upon them.
More deeply ingrained attitudes are like data files that remain intact in the matrix of the astral (energy) body of light. We are using light in modern technology as a transmitter of voice, data, and video signals. So it is not difficult to imagine a body of light in which a matrix of qualities, memories, tendencies, and attitudes reside.
Unlike computers, however, that which IS ("I AM"), the Infinite consciousness contains all thoughts, all past, present, and future. Thus in truth (in God's infinite consciousness) NOTHING is lost. But until our souls awaken and then merge into God, we only recover bits of data from our past. Hence it is that Patanjali in the Yoga Sutras explains that one who has achieved perfect non-attachment to his body and all objects remembers his past lives.
This does not mean that those children who are born with clear memories of the former life are necessarily great saints but, for reasons we cannot see, they are blessed with that memory perhaps to bestow a message to their families and others with "eyes to see."
Thus we mustn't feel badly to the degree of our grief and sense of loss, whether for ourselves or for others at the time of death. We can strive, however, to live with faith and to live on the higher plane of God-realization, compassion, concentration, and nobility of character. From the great heights of the mountain peaks of consciousness beyond bodily identification, we see the valleys and hills of life below as one great panorama.
