The first limb of yoga is the Yamas, five ways of treating others. In Vivekananda's translation, they are non-killing, truthfulness, non-stealing, continence and non-receiving.

Non-killing, or ahimsa, means not hurting others, in actions, words or even thoughts. It is the reason many yogis are vegetarian, and why Gandhi used ahimsa as his way of protest.

Truthfulness means being honest. Non-stealing means not taking what isn't yours. That includes things like taking credit for someone else's work.

Continence means self-control, especially over strong desires. Non-receiving means not grabbing more than you need, and not accepting gifts that come with hidden strings.

Why does yoga start here? Because it is very hard to have a peaceful mind when you are hurting people, hiding lies or always wanting more. These five clear away a lot of inner noise.

Pick one to practice this week. Many people find truthfulness is the best place to start.
