You, the self (also known as spirit or soul), is an entity that makes good or bad choices. These choices are passed on to your mind and the decisions you make are executed by your body. Unless God decides you should do otherwise. Every few seconds in your life, you have a choice, to do good or bad.
A healthy spiritual energy field is one where your body and mind act in accord with the five laws of ethics, called “yama” in Indian philosophy. These laws are:
• non-injury
• truthfulness
• non-misappropriation
• celibacy
• non-acceptance of gifts (beyond one's immediate needs)
You have a spiritual disease if you are breaking the laws of ethics.
Your spiritual discipline consists very simply of complying with the principles of yama. Your spiritual journey consists of your attempt to come into contact with your soul: yourself.
