A teaching by Siddhartha Gautama "The Buddha"(563 - 483 B.C) that teaches that eradication of the "self" illusion, extinguishment of material attachments and eradication of sensual cravings is the path to liberation (nirvana). Buddhism is perhaps the religion with the strongest scientific backing, with Albert Einstein once famously saying that Buddhism was the religion he favored most. It is believed that The Buddha referred to sub atomic particles and intra atomic forces long before any Western scientist. Some argue that "Buddhism" is not really a religion as it does not require worship to a God.
To the great credit of Buddhism, not a drop of blood has been shed in the name of The Buddha, in the faith's 2500 year history.
