Lord Krishna is the originator of this science who gave this knowledge at the time of "Origin of Srishti the Creation", to Lord Sun who gave to his Son Manu who gave it to his son Ishwaku, the ancestor of Lord Rama and in whose family and generations it remained for long time. Lord Krishna suggests the correct word the "practice of meditation" for meditation. He says in Gita, that the practice makes a man perfect. Without practice there cannot be the experiences. Mediation will guide how to know within, the real self, the real potential, the inner libration, the pathways and God.

That is, one remains still, yet attains his goal-the ultimate of life.
