Śaṅkarācārya's commentary

I am not manifest to all people; that is to say, I am manifest only to a few who are My devotees. I am veiled by Yoga-Māyā. — Yoga-Māyā is the Māyā which is none other than the Yoga or union of the three guṇas. — Or, Yoga is the firm will of the Lord or Īśvara. The Illusion or veil thereby spread is called Yoga-Māyā. — Wherefore people are deluded and know Me not as unborn and imperishable. That Yoga-Māyā by which I am veiled and on account of which people do not recognise Me, is Mine, i.e., subject to My control, and, as such, it cannot obstruct My knowledge — the knowledge of the Īśvara, of the possessor (or wielder) of the Māyā, just as the glamour (māyā) caused by a juggler (māyāvin) does not obstruct his own knowledge.
