In the “The Yoga Sutras of Patanjali”, Patanjali describes Yama as abstinence (or Ethical Behaviors) consisting of non-violence (ahimsa), truthfulness (satya), non-stealing (asteya), continence (brahmacharya), and non-greed (aparigraha).
Ahimsa is not only about non-violence in the broad definition, but in a smaller definition it also means things like not causing pain; himsa meaning pain, so a-himsa is without pain. This is to include non-physical pain as well; name calling, gossiping, even your thoughts could cause pain either to yourself or to others.
Satya or truthfulness means not lying. Half truths, withholding information, and so on are all variations of not telling the truth.
Asteya or non-stealing this means of physical things as well as someones time, energy, etc. Or also misuse of someone or your own time, energy, etc.
Brahmacharya, continence or celibacy, often referred to as control of the senses. Restraining from indulging in sexual gratification.
Aparigraha or non-greed. To include hoarding, accumulating beyond our means or capacity, and not using things improperly.
