A mother knows what her child's cry means — not from a textbook, but from the heart. The knowing Krishna speaks of here is that kind: not intellectual analysis but deep, felt understanding. Whoever truly grasps that My birth and actions are divine — not ordinary, not forced by karma — that person, upon leaving the body, is not born again. He comes to Me.
This is not casual knowledge. It is the kind of understanding that transforms a person from the inside. When someone sees Krishna's incarnation as a divine act of love rather than a mundane event, something shifts in them. The cycle of birth and death loosens its grip.
