The son of Vajranābha was Sagaṇa, and his son was Vidhṛti. The son of Vidhṛti was Hiraṇyanābha, who became a disciple of Jaimini and became a great ācārya of mystic yoga. It is from Hiraṇyanābha that the great saint Yājñavalkya learned the highly elevated system of mystic yoga known as ādhyātma-yoga, which can loosen the knots of material attachment in the heart.
