The essence of the Buddha’s teaching can be summed up in two principles: the Four Noble Truths and the Noble Eightfold Path. The first covers the side of doctrine, and the primary response it elicits is understanding; the second covers the side of discipline, in the broadest sense of that word, and the primary response it calls for is practice. In the structure of the teaching these two principles lock together into an indivisible unity called the dhamma-vinaya, the doctrine-and-discipline, or, in brief, the Dhamma.
