The Sanskrit word upaya (“expedient”) conveys the meaning of leading to or approaching the goal. The Three Vehicles are such expedients leading to the goal, the true teaching of the One Buddha Vehicle. Expedients are not just means to an end; they have significance in and of themselves. They are valid steps in the process leading to the truth, the insight of the Buddha. Conversely speaking, the One Buddha Vehicle (the final single truth) is revealed in the form of expedient teachings, valid according to the complexity of our world view. So the sutra says, “The Buddhas divide the One Buddha Vehicle into three as an expedient” (p. 33).

Thus expedients equal the truth in essence. It is not true that “a white lie can be an expedient.” A lie, white or black, is not an expedient in the Buddhist sense. An expedient is true within its own context.
