“The Dhammapada, an ancient Buddhist text..says:
‘What you are now is the result of what you were. What you will be tomorrow will be the result of what you are now. The consequences of an evil mind will follow you like the cart follows the ox that pulls it. The consequences of a purified mind will follow you like your own shadow. No one can do more for you than your own purified mind— no parent, no relative, no friend, no one. A well-disciplined mind brings happiness.’
Meditation is intended to purify the mind. It cleanses the thought process of what can be called psychic irritants, things like greed, hatred, and jealousy, which keep you snarled up in emotional bondage. Meditation brings the mind to a state of tranquillity and awareness, a state of concentration and insight.
Meditation changes your character by a process of sensitization, by making you deeply aware of your own thoughts, words, and deeds. Your arrogance evaporates, and your antagonism dries up. Your mind becomes still and calm. And your life smoothes out. Thus meditation, properly performed, prepares you to meet the ups and downs of existence.”
