In Buddhism
Mahayana (major branch of Buddhism)
Source: Wisdom Library: Maha Prajnaparamita SastraUdraka (उद्रक) is the name of a Ṛṣi according to the 2nd century Mahāprajñāpāramitāśāstra (chapter XXVIII). Accordingly, “Thus, the Ṛṣi Yu t’o lo k’ie (Udraka) who possessed the five superknowledges (abhijñā), each day flew to the palace of the king where he took his meal. The king and queen, according to the custom of the land, greeted him by placing their head at his feet. The queen having touched him with her hand, the Ṛṣi Udraka lost his abhijñās. Unable to fly, he asked the king for a chariot and drove away. Returning home, he went into a forest and tried to retrieve his five abhijñās”.
Note: This Udraka is certainly the Udraka Rāmaputra who taught Gautama the path of naivasaṃjñānāsaṃjñāyatana; finding this teaching inadequate, the future Buddha abandoned it. The story that the Mahāprajñāpāramitāśāstra devotes to Udraka tells us that this ascetic took rebirth in the sphere of neither discrimination nor non-discrimination before falling into hell. The text of the Mahāprajñāpāramitāśāstra is reproduced without any changes in the King liu yi sinag. A more detailed version of the same story occurs in the Vibhāṣā in 60 scrolls.

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
Tibetan Buddhism (Vajrayana or tantric Buddhism)
Source: 84000: Samādhirājasūtra (The King of Samādhis Sūtra)Udraka (उद्रक) (also known as Rudraka) represents one of the first teachers of the Buddha, as mentioned in the Samādhirāja-sūtra verse 9.43.—Accordingly, “If you meditate on a worldly samādhi, And do not eliminate the conception of a self, Then the kleśas will arise once more, As happened in the samādhi practice of Udraka”.
Note: The commentary states that Udraka was also known as Digambhara [Digambara], which is also the name of a Jain school. However, the name Udraka (Rudraka in some texts) is best known in Buddhism as one of the first teachers of the Buddha. The Buddha stated that after death he was born in the formless realm but would eventually be reborn as an animal. The story for Udraka given in the commentary is that his motivation to meditate was to attain miraculous powers. He succeeded and was famous for being able to fly. But when he was told that his path was not genuine, he fell from the sky and went to the hells.

Tibetan Buddhism includes schools such as Nyingma, Kadampa, Kagyu and Gelug. Their primary canon of literature is divided in two broad categories: The Kangyur, which consists of Buddha’s words, and the Tengyur, which includes commentaries from various sources. Esotericism and tantra techniques (vajrayāna) are collected indepently.
