Students of popular science... are always insisting that Christianity and Buddhism are very much alike, especially Buddhism. This is generally believed, and I believed it myself until I read a book giving the reasons for it.
The convent, which belongs to the West as it does to the East, to antiquity as it does to the present time, to Buddhism and Muhammadanism as it does to Christianity, is one of the optical devices whereby man gains a glimpse of infinity.
Buddha himself taught different teachings to different people under different circumstances. For some people, there are beliefs based on a Creator. For others, no Creator. The only "definitive truth" for Buddhism is the absolute negation of any one truth as the Definitive Truth.
Buddha taught kindness towards lower beings; and since then there has not been a sect in India that has not taught charity to all beings, even to animals. This kindness, this mercy, this charity - greater than any doctrine - are what Buddhism left to us.
