1. For World Yoga Day (21 June) — the highest yoga

    It is very difficult to push on this movement, but still we have to do it. And this is the highest yoga. If you push on this movement of Krsna consciousness, then you'll be performing the highest type of yoga. Don't be misled by so-called yogas. This is yoga. Yoga means cooperation, cooperation with the Supreme.

    From Srila Prabhupada's lecture on Bhagavad-gita 7.1 — March 17, 1968, San Francisco
