PURPORT

Yoga is a means to understand the Supreme Soul. One who is steadily fixed in the Supreme Soul with determination, concentrating one's mind, life and sensual activities on the Supreme, engages in Krsna consciousness. That sort of determination is in the mode of goodness. The word avyabhicarinya is very significant, for it refers to persons who are engaged in Krsna consciousness and are never deviated by any other activity.
