“The greater the Śraddhā, the more meaning there is in the techniques such as Āsana, Prāṇāyāma, Dhyānam, Bhāvana and all the others. Without Śraddhā, these techniques have little effect on the state of the mind and the progress to Citta Vṛtti Nirodha.

However, sometimes some minor benefits that we get through Āsana or Prāṇāyāma practice, open up the Śraddhā within us. Śraddhā is within each of us but is covered. It could be any experience that uncovers it.”

– TKV Desikachar on Śraddhā in the Yoga Sūtra
