The Heart Sutra is the most common text in the Mahayana Buddhist tradition. It is part of the Prajnaparamita Sutras, a collection of sutras composed between 100 BCE and 500 CE (the Buddha’s second turning of the wheel of Dharma). Some practitioners say the Heart Sutra is a distillation of all the Prajnaparamita Sutras. The Heart Sutra is a presentation of profound wisdom on the nature of emptiness.
