Śaṅkarācārya's commentary

Those Bhaktas who fix their mind on Me in the Universal Form, the Supreme Lord, and worship Me as the Governing Lord of all Masters of Yoga, who is omniscient, whose vision is free from the timira (purblindness) of attachment and other evil passions — they who always contemplate Me steadfastly (in the manner described in the closing verse of the preceding Discourse), endowed with supreme faith — these, I think, are the best Yogins. Indeed, they pass their days and nights in incessant thought of Me. Wherefore it is but proper to speak of them as the best Yogins.
