Austerity, study, and the dedication of the fruits of one's work to God: these are the preliminary steps toward yoga.

The practice of Yoga must reduce both physical and mental impurities. It must develop our capacity for self-examination and help us to understand that, in the final analysis, we are not the masters of everything we do.

Yoga in the form of action (kriya yoga) has three parts: 1) training and purifying the senses (tapas), 2) self-study in the context of teachings (svadhyaya), and 3) devotion and letting go into the creative source from which we emerged (ishvara pranidhana).
