What is a simple barometer to measure our purity daily?
Hands are not the only limbs or agents that are involved in Karma or human activity. Whatever is done, seen or heard, one should be vigilant about its purity. Thought, word and deed must be free from pride, greed and hatred. The words that one utters must be free from these faults. Things that one yearns to hear must be free from these superficially attractive qualities; the pleasures that one seeks must not be polluted by evil. You must first assimilate these mental lessons and demonstrate their effect in your speech. You must translate this lesson taught by words into action.
