Yamas and niyamas
The yamas and niyamas are the ten ethical guidelines that open the eight limbs of yoga in Patanjali's Yoga Sutras. The five yamas describe how you treat others and the world, and the five niyamas describe how you look after yourself.
Where they come from
The yamas and niyamas come from the Yoga Sutras, a short text of compact sayings traditionally credited to Patanjali. Scholars usually place its compilation somewhere in the early centuries of the common era, though the dating is debated. In the second chapter, the Sutras lay out eight limbs of practice, and the yamas and niyamas are the first two. Postures come third, breathing fourth, and the inner practices of concentration and meditation follow.
That order matters. In the classical text, ethics come before the body, and a gentle start with a private teacher works the same way: how you treat your body comes before how far it goes. The Sutras also say that the yamas become a great vow when they are kept everywhere and always, without exceptions for place, time or circumstance. Later commentators wrote at length on each one, and much of what modern teachers say about them is handed down through those commentaries.
The five yamas
- Ahimsa, non-harming. Often placed first, and often read as the root of the other yamas.
- Satya, truthfulness, in speech and in how you present yourself.
- Asteya, not stealing, including time, credit and attention that are not yours.
- Brahmacharya, traditionally celibacy for the renunciant, now more often read as moderation of the senses and of energy spent.
- Aparigraha, not grasping, or not holding on to more than you need.
The five niyamas
- Saucha, cleanliness of body, space and mind.
- Santosha, contentment with what is here.
- Tapas, steady discipline, the effort that keeps a practice going.
- Svadhyaya, self-study, which classically includes the study of texts.
- Ishvara pranidhana, surrender or devotion to something larger than yourself.
The last three niyamas also appear earlier in the same chapter, where the Sutras call them kriya yoga, the yoga of action.
How they show up in a modern practice
Most people meet the yamas and niyamas on the mat rather than in the text. Ahimsa is the reason a good teacher tells you to back off before pain, not after it. Satya is being honest about how your body feels today rather than how it felt last month. Santosha is letting a pose be what it is without forcing the next version. Tapas is turning up on the days you would rather not, the practice followed long and with earnestness that one of the best-known yoga quotes from the Sutras describes.
Some teachers choose one yama or niyama as the theme for a class. Others never name them at all and simply teach in a way that reflects them. Both are common, and neither is more correct.
How they can come up in a private lesson
In a private lesson there is room to ask how your body is actually doing, and that is where these ideas stop being abstract. A lesson might be built around ahimsa by keeping every shape well inside what feels safe, or around santosha by staying in one gentle posture and noticing it rather than chasing depth. If you are curious about the philosophy, we can talk about it; if you are not, the principles still shape how the lesson is taught.
