Suramgamasamadhi sutra

The Śūraṅgama Samādhi Sūtra (Sanskrit; traditional Chinese: 首楞嚴三昧經; simplified Chinese: 首楞严三昧经; pinyin: Shǒuléngyán Sānmèi Jīng; Wade–Giles: Shou-leng-yen San-mei Ching) is an early Mahayana sutra of Indian origin which focuses on the transcendental nature, supernatural powers, and transformational feats bestowed upon the meditation practitioner by the state of meditation called the "Śūraṅgama Samādhi" or the "Samādhi of the Heroic Progression."

The Śūraṅgama Samādhi Sūtra was translated from the Sanskrit into Chinese by Kumārajīva probably between 402 and 409 C.E. and was later translated into Tibetan by Sakyaprabha and Ratnaraksita at the beginning of the 9th century.

Professor Lamotte describes the nature of the Buddha in this sutra as follows:

This is Sakyamuni in Heroic Progress, a pure ray of wisdom and power, who manifests himself simultaneously in our little universe of four continents, in the Great Cosmos ... and in all the great cosmic systems ...; there, he is some divinity .... He is the same as the Buddha Vairocana.

The sutra describes the 100 powers and abilities which the Buddha or 10th-level Bodhisattvas can perform, while operating from within this samādhi state.

Amongst the wonders which the Buddha can perform whilst in this state of Śūraṅgama Samādhi are:

Part of that profound and unfathomable knowledge is that all dharmas (things) have their basis in the dharma-dhatu - the Totality of all that is, the All. In this sense, there is non-duality that characterises everything, since everything is possessed of the 'one flavour' of the dharma-dhatu. The Buddha states:

A bodhisattva knows that all dharmas rest eternally on the fundamental element (dharmadhatu) without coming or going.
