“ In the vajrayana, there is an emphasis on upaya, or skillful means. In fact, one of the definitions of vajrayana is that it is composed of teachings based on a particular state of mind or mental approach, in which shunyata and prajna are put together and are regarded as upaya. So the combination of the emptiness nature of the phenomenal world and clear seeing is regarded as great compassion, which is considered to be a skillful means.”
