Practice vs.knowledge

Liam: Are you bringing all those books at the yoga seminar with Gurudev?

Leo: Absolutely! I’m almost done with The Yoga Sutras by Patanjali and I’m reading the Tao of Physics, next. There are also some passages of Yogananda’s Autobiography of a Yogi that I think I need to read again.
Did you know that Yogananda wrote a commentary to the Gospels? I’d like to read that, too. I’ll see if I can find it on Amazon…

Gurudev: …so my dear ones, keep practicing! Practice! practice! practice! A gram of practice is worth more than a ton of knowledge!
