If science proves facts that conflict with Buddhist understanding, Buddhism must change accordingly. We should always adopt a view that accords with the facts.
Buddha was speaking about reality. Reality may be one, in its deepest essence, but Buddha also stated that all propositions about reality are only contingent. Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness." Therefore, Buddhism strongly discourages blind faith and fanaticism.
One should not kill a living being, nor cause it to be killed, nor should one incite another to kill. Do not injure any being, either strong or weak, in the world.
There has to be evil so that good can prove its purity above it. To live a pure unselfish life, one must count nothing as one's own in the midst of abundance.
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.
To define Buddhism without a lot of words and phrases, we can simply say, 'Don't cling or hold on to anything. Harmonize with actuality, with things as they are.'
The whole secret of existence is to have no fear. Never fear what will become of you, depend on no one. Only the moment you reject all help are you freed. - Buddha No one saves us but ourselves. No one can and no one may. We ourselves must walk the path.
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.
Each religion has helped mankind. Paganism increased in man the light of beauty, the largeness and height of his life, his aim at a many-sided perfection; Christianity gave him some vision of divine love and charity; Buddhism has shown him a noble way to be wiser, gentler, purer, Judaism and Islam how to be religiously faithful in action and zealously devoted to God; Hinduism has opened to him the largest and profoundest spiritual possibilities.
