"There are three kinds of violence: one, through our deeds; two, through our words; and three, through our thoughts. ... The root of all violence is in the world of thoughts, and that is why training the mind is so important." -- Eknath Easwaran
"The ancestor of every destructive action, every destructive decision, is a negative thought." -- Eknath Easwaran
"We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far." -- Swami Vivekananda
