Yoga Sutra ~ Self-study

Self-study - Svadyaya is one of the five niyamas. 

Niyama means personal observances or attitudes. 

Yoga Sutra ch. 2, v. 44:
“Self-study (Svadyaya) leads to awareness, communication and union with spirit.” 

Self-study is when we look within. It’s when we are present to how and what we feel. It’s a form of respectful observation and listening to ourselves.
