I prefer the word “Sraddha”

Sraddha in the practice. Sraddha in the teaching. Sraddha in life’s healing powers.

Inspired from “ Yoga of the Yogi” by Kausthub Desikachar

The ancient masters always tested the faith of each student before agreeing to teach them. If the student had no faith, then any practice they chose to teach that student would not work.
