Today I fielded this question from a Hindu in the United States:
"I have read from many sources, that Hinduism or originally known as Sanatana Dharma, the eternal way is non-sectarian, and can be applicable to anyone regardless of religion or race. I am Hindu, but don’t understand how the Bhagavad Gita for instance is non-sectarian, as Lord Krishna Himself says he is the Supreme God. I don’t see how a Christian/Muslim would be able to agree? Some of the teachings are universal, but many other religions do not believe in reincarnation either. Please clarify."
