Jñānaketu (ज्ञानकेतु) is the name of a Buddha under whom Śākyamuni (or Gautama, ‘the historical Buddha’) acquired merit along the first through nine bhūmis, according to the Mahāvastu. There are in total ten bhūmis representing the ten stages of the Bodhisattva’s path towards enlightenment.

Jñānaketu is but one among the 500 Buddhas enumerated in the Mahāvastu during a conversation between Mahākātyāyana and Mahākāśyapa, both principle disciples of Gautama Buddha. The Mahāvastu is an important text of the Lokottaravāda school of buddhism, dating from the 2nd century BCE.

Jñānaketu (ज्ञानकेतु) is one of the sixteen bodhisattvas appearing in the Vajradhātu-mahāmaṇḍala, according to the Nāmamantrārthāvalokinī v5.38-41. The Nāmamantrārthāvalokinī (literally, ‘an explanation of the nāma-mantras’) is a commentary (ṭīkā) on the 8th century Mañjuśrīnāmasaṃgīti.

Jñānaketu is a name of Mañjuśrī (the embodiement of non-dual knowledge) and, together with other names, forms the core essence of the Mañjuśrīnāmasaṃgīti. The Nāmamantrārthāvalokinī provides the practitioner a sādhana (‘meditative practice’) to turn these names into mantras. These mantras are chanted for the benefit of all beings, and then placed and contemplated in the Vajradhātu-mahāmaṇḍala, which is an extended version of the Vajradhātu-maṇḍala.

Jñānaketu (ज्ञानकेतु) is the name of a Bodhisattva commonly depicted in Buddhist Iconography, and mentioned in the 11th-century Niṣpannayogāvalī of Mahāpaṇḍita Abhayākara.—his color is yellow or blue; his symbol is the flag with cintāmaṇi jewel.—Jñānaketu occurs only once in the Chinese collection, where his form is identical with his sire Ratnasambhava.

Jñānaketu is described in the Niṣpannayogāvalī as follows:—

(1: Mañjuvajra-maṇḍala):—“Jñānaketu is yellow in colour. He holds in his right hand the flag marked with the Cintāmaṇi jewel. The left hand displays the Varada-mudrā”. (2: Durgatipariśodhana-maṇḍala):—“Jñānaketu is blue in colour. He holds in his right hand the flag marked with the Cintāmaṇi jewel. The clenched left hand rests on the hip”.
