Dhāraṇīśvararājasūtra

Dhāraṇīśvararājasūtra (T. 'phags pa de bzhin gshegs pa'i snying rje chen po nges par bstan pa zhes bya ba theg pa chen po'i mdo; C. 大哀經), Questions of Dhāraṇīśvararāja Sūtra, is a Mahayana sutra that is counted among the sutras associated with tathāgatagarbha.

Also known as The Sūtra Teaching the Great Compassion of the Tathāgatas (Tathāgatamahākaruṇānirdeśasūtra), this lengthy sūtra is stated to be the primary source for the Ratnagotravibhāga since it touches upon all seven vajra topics discussed in the treatise.
