If Buddhists themselves cannot agree on which scriptural writings or traditions for practice are actually true statements from the Buddha, how can Buddhism as a system claim any truth?
The above question raised due to there are many articles discussing, or discrediting the authenticity of some Sutras/Suttas and doctrines. Since the Buddha never written down his teachings himself, how does the Buddhist scriptures transmit from the Buddha to us according to historical documentation, text, or evidence?
By saying "Buddhism as a system" I meant what is the original content of Buddhism through investigating the original scriptures' transmission history. In this way we can discern what teaching is included in the original content; and what is excluded even missing from the original content, i.e., outside the system.
