Spiritual awakening is a process of remembrance (smriti is the term Patanjali uses in the Yoga Sutras). The guru awakens both a remembrance and the desire for liberation. Hence: the goal! All desires must be fulfilled by the law of prana (energy) and creative visualization.
Ignorance is the source of suffering and ignorance results from mistaking the unreal for the real. The unreal has apparent reality only by the flux of opposites and includes such qualities as egoism, attachment, aversion and (blind) tenacity.
Swami Sri Yukteswar then gives a more detailed analysis of this process. He starts with the statement that ignorance produces a sense of separateness of objects (egoism) and the consequent tenacious power (desire) of holding one's form separate and apart. From this comes the attraction to or repulsion away from other objects.
