The reflection, the verisimilitude, of life that shines in the fleshly cells from the soul source is the only cause of man's attachment to his body; obviously he would not pay solicitous homage to a clod of clay. A human being falsely identifies himself with his physical form because the life currents from the soul are breath-conveyed into the flesh with such intense power that man mistakes the effect for a cause, and idolatrously imagines the body to have life of its own.
Paramahansa YoganandaLord Krishna... proclaims Self-realization, true wisdom, as the highest branch of all human knowledge-the king of all sciences, the very essence of dharma ("religion")-for it alone permanently uproots the cause of man's threefold suffering and reveals to him his true nature of Bliss. Self-realization is yoga or "oneness" with truth-the direct perception or experience of truth by the all-knowing intuitive faculty of the soul.
