The Mañjuśrī-mūla-kalpa is text of the class designated as Kriyā-tantra. It is closely aligned and identified with the bodhisattva Mañjuśrī. This Mañjuśrī-mūla-kalpa is often cited as the earliest example of an extant Indian Buddhist Tantra. Some scholars identify it as a compilation of a core dated circa 6th century with accretions and additions. The Sanskrit version, significantly longer than its corresponding Chinese and Tibetan renderings, is still extant.
