Though the ādheyas are of many kinds and their uses are of many kinds, the ādhāra is one alone. Just as the current is the ādhāra, even so, in all upādhis, it is that Parātpara who is the giver of the fruit of all karma. Like the current, the Parātpara dwells as the inner Ātma of all beings and is the doer of all karma; and so He Himself is the adhiyajña.
