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; Vietnamese: Kinh Thủ Lang Nghiêm Tam Muội) is an early Mahayana sutra of Indian origin[1] 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."
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 element of phenomena.
The Buddha states: A bodhisattva knows that all dharmas rest eternally on the fundamental element (dharmadhatu) without coming or going.
[8]Even the writing down, studying and teaching of this Śūraṅgama Samādhi by a master of Dharma will bestow immense blessings, twenty in number.
These include: One of these powers is demonstrated by the future Buddha, Maitreya, who transforms himself into innumerable different types of leading spiritual personages in countless world-systems at the same time.
