There are many interpretations of and opinions about the yamas and niyamas. While the ancient Indian text, the Bhagavata Purana assigns 12 yogic restraints the Parashar Smriti, another text, puts forward ten. But the yamas as described in Patanjali's Yoga Sutra are only five, which are also known as the great universal vows or the sarvabhauma maha vratas, because they are not limited by either class, creed, time or circumstances. They are the guidelines for how we interact with the outer world, the social disciplines to guide us in our relationships with others. These five are:

1. Ahimsa (non-violence)

2. Satya (truthfulness)

3. Asteya (non-stealing)

4. Brahmacharya (celibacy)

5. Aparigraha (non-covetousness)
