The Heart Sūtra or Sherap Nyingpo (ཤེས་རབ་སྙིང་པོ་) is one of the most popular Buddhist sūtra and certainly among the most widely used and chanted sutra-s in Tibet. Its full title in Sanskrit is Bhagavatīprajñāpāramitāhṛdaya and in Tibetan བཅོམ་ལྡན་འདས་མ་ཤེས་རབ་ཀྱི་ཕ་རོལ་ཏུ་ཕྱིན་པའི་སྙིང་པོ་ which translates as The Heart of the Blessed Perfection of Wisdom.
