Yacana is a Sanskrit term that means “supplication.” It is one of the spiritual exercises that comprise anuttara puja, also known as “supreme worship” or “seven-fold worship.” Anuttara puja is a method of devotion developed by the seventh-century Indian master, Shantideva. It consists of seven spiritual exercises and is typically practiced in the Buddhist tradition.

Yacana is a plea or a prayer asking the Buddha to not abandon the world and its inhabitants. It indicates that the petitioner is receptive to the teachings of the Buddha. Yacana is sometimes considered synonymous with adhyesana (prayer), although some sources list them as separate exercises in the supreme worship.
