ethics and conduct
What is asteya (non-stealing) and how does it apply beyond physical theft?
What asteya means
The word asteya comes from Sanskrit. 'A' means not, and 'steya' means theft. So asteya is simply non-stealing. In the Yoga Sutras, Patanjali lists it as the third yama, one of the core ethical restraints that a person is meant to live by. It sits alongside ahimsa (non-harm) and satya (truthfulness) as a basic rule for how to move through the world. The tradition treats it not as a legal rule but as an inner discipline. Even the desire to take what belongs to someone else is seen as a form of stealing.
Beyond taking objects
The Mahabharata and other texts in the tradition stretch asteya well past physical theft. Taking credit for someone else's work is seen as a form of stealing. So is wasting another person's time, using their energy or attention without care, or claiming ideas that came from someone else. Coveting what another person has — even just sitting with that wanting — is treated as a subtle form of the same problem. The tradition also includes misusing resources that belong to a community or employer, taking more than your fair share, or accepting something you have not earned. In this reading, asteya is less about the hand and more about the mind.
How the idea developed
Texts like the Manusmriti discuss honesty in dealings and the wrongness of misappropriation in ways that go beyond simple theft. The Mahabharata, which covers ethics across many situations, treats the impulse to take or covet as something that damages both the person who does it and the people around them. These ideas were not new inventions. They built on a long tradition of seeing ethics as something lived in small daily choices, not just in big moments.
How people think about it today
Many people today find asteya useful precisely because it reaches into everyday life. Copying someone's work without acknowledgement, running late and using up another person's time, or taking more than you need from shared spaces — these are the kinds of situations where the idea still feels relevant. Different families and communities emphasise different parts of it. Some focus on honesty in business. Others focus on the inner attitude of contentment, the sense that what you have is enough. The two are connected in the tradition: a person who is genuinely content has less reason to take what is not theirs.
