Śaṅkarācārya's commentary

"By Me presiding": as a mere viewer on every side and the immutable witness. My Māyā, i.e., the Avidyā composed of the three guṇas, produces the universe comprising the moving and the unmoving objects. The chant says: "The one, the luminous, hidden in all beings, all-pervading, the Inner Self of all, the superintendent of all acts, the abode of all beings, the witness, the perceiver, alone, and free from qualities" (Śvet. Up. 6.11). Because I am the witness, because I preside, this universe comprising the moving and the unmoving objects, the manifested and the unmanifested, moves on through all stages.
