“It is action that makes a person great. Be great by your sádhaná, by your service, by your sacrifice.” — Shrii Shrii Anandamurti

This is a quote from my spiritual teacher. He always emphasized action as opposed to theory and said that yoga is 90% action and 10% theory. So, there is no need to read tons of books on the subject. Rather, you should do your spiritual practices (sadhana), serve other human beings and make some sacrifices for the good of humanity. Lots of good advice in a single sentence. Enjoy your day!
