The Āryamañjuśrīmūlakalpa (The Noble Root Manual of the Rites of Mañjuśrī) is a Mahāyāna sūtra and a Mantrayāna ritual manual (kalpa) affiliated with the bodhisattva of wisdom, Mañjuśrī. In Tibetan Buddhism it is classified as a Kriyā-tantra. According to Sanderson (2009: 129) and the study by Matsunaga (1985), the text is datable to about 775 CE.
The Mañjuśrīmūlakalpa is often cited as the earliest example of an extant Indian Buddhist Tantra. Some scholars identify it as a compilation of a core verse text dated circa 6th century CE with later accretions and additions. The Sanskrit version, significantly longer than its corresponding Chinese and Tibetan renderings, is still extant.
