Acharya Sakyaprabha was born into a royal caste between the seventh and eighth centuries in the western part of India. He became a monk and took the vow of bhikshu from Nalanda abbot Punyakirti. He studied three collections of Buddha teachings, relying on teachers like the Magadhan abbot Punyakirti and Acharya Shantiprabha, and became a supreme expounder of Vinaya texts. With Acharya Vajrahasa he studied tantric texts and became a great scholar known as Prabhahati, achieving supreme siddhis. In Nalanda monastic college, he composed vinaya texts such as the Three Hundred Stanzas and its auto-commentary Lustrous, and verses of instructions of the novice monk. These and others of his more than five volumes of texts are translated into Tibetan. He went to Kashmir and worked extensively for the welfare of beings. Being highly learned in vinaya, he expanded the Sangha and he trained many disciples abiding in the training of discipline who accomplished great works for the teachings and sentient beings, such as Sakyamitra, Acharya Padmasambhava, Jinamitra, and so forth. He had the vision of Shri Manjhughosha. From the six ornaments and two supreme ones that beautify the Jambu continent, Acharya Gunaprabha is known as one of the two supreme ones, worthy to sit on Buddha’s left side, because he thoroughly completed the study and contemplation of Buddha's treasure teachings of Vinaya. While working fervently for the discipline that forms the foundation of Buddha’s teachings, he passed into nirvana.
