In India, the equivalent of "peace" is "santi" which means the highest state of inner tranquility. It also means the enlightened condition attained by Shakyamuni sometimes referred to as "nirvana."A Buddhist scripture describes the state of inner peace as follows: "Tranquility of mind comes from having successfully transcended greed, hatred and ignorance." In the state of tranquility, the light of enlightened wisdom shines brilliantly, unblocked and unhindered by the clouds of deluded impulses. Each human being exists within the context of interrelationships that include other human beings, all living beings and the natural world. In other words, each person is sustained by the interdependent web of life. By awakening to this principle we are able to expand instinctive self-love into an altruistic love for others; we are able to nurture the spirit of tolerance and empathy for others. The doctrine of dependent origination serves as a theoretical foundation for peace.
