The Heart Sutra(བཅོམ་ལྡན་འདས་མ་ཤེས་རབ་ཀྱི་ཕ་རོལ་ཏུ་ཕྱིན་པའི་སྙིང་པོ) is the most widely known sutra of the Mahayana tradition of Tibetan Buddhism. It is part of the Prajnaparamita Sutras, which is a collection of about 40 sutras composed between 100 BCE and 500 CE. The Heart Sutra is a presentation of profound wisdom on the nature of emptiness. The Sutra famously states, "Form is emptiness (śūnyatā), emptiness is form." It is a condensed exposé on the Buddhist Mahayana teaching of the Two Truths doctrine, which says that ultimately all phenomena are sunyata, empty of an unchanging essence. This emptiness is a 'characteristic' of all phenomena, and not a transcendent reality, but also "empty" of essence of its own. Specifically, it is a response to Sarvastivada's teachings that "phenomena" or its constituents are real. It has been called "the most frequently used and recited text in the entire Mahayana Buddhist tradition." The text has been translated into English dozens of times from Chinese, Sanskrit, and Tibetan as well as other source languages.
