Heart Sutra (English)
Thus did I hear at one time. The Bhagavan was dwelling on Mass of Vultures Mountain in Rajagriha together with a great community of monks and a great community of bodhisattvas. At that time, the Bhagavan was absorbed in the concentration on the categories of phenomena called "Profound Perception."
Also, at that time, the bodhisattva mahasattva arya Avalokiteshvara looked upon the very practice of the profound perfection of wisdom and beheld those five aggregates also as empty of inherent nature.
