The Suryagarbha Perfection of Wisdom
This sutra, The Suryagarbha Perfection of Wisdom ( Skt. Sūryagarbhaprajñāpāramitā; Tib. ཤེར་ཕྱིན་ཉི་མའི་སྙིང་པོ།, Wyl. sher phyin nyi ma’i snying po) , is a condensed prajnaparamita sutra in the form of a dialogue between the Buddha and the bodhisattva Suryaprabhasa, who asks the Buddha how bodhisattvas skilled in means should train themselves in the perfection of wisdom. In response, the Buddha explains that a bodhisattva should train in a meditative stability called the sun or the sun skilled in means, elaborating upon the qualities of this meditative stability using the analogy of the sun in terms of seven qualities. He then further describes the training of the bodhisattva in the perfection of wisdom as training concerning the true nature of all phenomena, which is characterized in familiar terms found in the long prajñaparamita sutras. It is also described in terms of the various designations for ultimate truth. Finally, the Buddha enumerates the characteristics of the one who trains in the perfection of wisdom, ending with a verse of instruction.
