Which of the following is NOT one of the five Yamas?

The five Yamas are ethical precepts in yoga philosophy that guide an individual's interactions with others and the world at large. These principles are rooted in the first limb of Patanjali's Eight Limbs of Yoga, focusing primarily on moral and ethical behavior.

Ahimsa refers to non-violence and compassion towards all living beings. Aparigraha signifies non-greed or non-attachment to possessions. Asteya means non-stealing or not taking that which is not freely given. These three are indeed foundational components of the Yamas.

Santosha, however, is not part of the Yamas; it is one of the Niyamas, which focus on a person's relationship with oneself. Santosha translates to contentment and represents the idea of being at peace with what one has, which is crucial for personal development and happiness but is categorically different from the ethical constraints outlined in the Yamas.

This distinction between the Yamas and Niyamas is essential to understand the broader ethical teachings of yoga and how they differentiate between interpersonal ethics and personal observances.
