The History of Buddhist Thought c15.41

c15.41

When we come to the question of the actual doctrines which may have been borrowed, we find that they are claimed to be not in the Upanishads, but in the philosophical schools of Yoga and Sāṅkhya. In the case of Yoga, as we have seen, it is rather a method of training which is in question. Some form of Yoga no doubt preceded Buddhism, and some of the particular methods may have been borrowed, but as the Buddhist system continued to grow we can in no case be sure that these belonged to original Buddhism. We have seen what is supposed to have been borrowed from Sāṅkhya. Even if the evidence for the borrowing of the Causal Formula were more cogent, we should have no reason to think that the Formula formed one of the foundations of the original system.²
