A: In the Yoga Sutras, Putanjali lists five yamas, hindrances, and five niyamas, observances, which make the the first two of his eight limbs of yoga. The yamas teach us how to treat others and the niyamas teach us how to treat ourselves. They are as follows:

Yamas
1. Ahimsa – Nonviolence
2. Satya – Truthfulness
3. Asteya – Nonstealing
4. Brahmacharya – Moderation or Sexual Responsibility
5. Aparigraha – Non-possessivenes

Niyamas
1. Saucha – Purity
2. Santosha – Contentment
