In Buddhism
Mahayana (major branch of Buddhism)
Source: Wisdom Library: Maha Prajnaparamita SastraVimokṣamukha (विमोक्षमुख) refers to the “three gates of deliverance”, according to the 2nd century Mahāprajñāpāramitāśāstra chapter 40.—Accordingly: The Buddha utters the lion’s roar. He is like the king of the lions (siṃharāja). [...] The Buddha-lion is very similar. [...] The three gates of deliverance (vimokṣamukha) are the fore-part of his body with firm flesh. The three wonders are his long spine. The perfection of the sciences and practices is his invisible belly. Patience is his narrow waist. The practice of solitude is his long tail. The four foundations of magical power are his well-planted paws. The five faculties of the aśaikṣa are his sharp claws. [...]
Source: academia.edu: A Study and Translation of the GaganagañjaparipṛcchāVimokṣamukha (विमोक्षमुख) refers to the “(three) gates of liberation”, according to the Gaganagañjaparipṛcchā: the eighth chapter of the Mahāsaṃnipāta (a collection of Mahāyāna Buddhist Sūtras).—Accordingly, “How then, son of good family, does the Bodhisattva who has attained memory never forget? Son of good family, the Bodhisattva attains memory (dhāraṇī) by purifying his memory. What then is the purification of memory? Son of good family, there are thirty-two purifications of memory. What are the thirty-two? [...] (25) entering into what is to be done; (26) no fear reflecting on thoughts concerning the three gates of liberation (tri-vimokṣamukha); (27) never cutting off the [fourfold] sources of holiness by possessing the qualities of purity; (28) no despondency to uphold the true religion; [...]”.

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: Brill: Śaivism and the Tantric Traditions (tantric Buddhism)Vimokṣamukha (विमोक्षमुख) refers to the “(four) liberation faces”, according to the Nāmamantrārthāvalokinī by Vilāsavajra, which is a commentary on the Nāmasaṃgīti.—Accordingly, [while describing Mahāvairocana]—“And then [the Sādhaka should visualise] Mahāvairocana on the principal seat, generated by means of the syllable āḥ. [Why has he four faces?] Since consciousness—which is of the nature of the Dharma-Sphere since, by its nature, it lacks such forms as the grasped [i.e., the subject-object duality]—is four-faced. [This is] because the four liberation faces [/doors] (catur-vimokṣamukha)—emptiness and the rest—are the cause of the origination of all meditative concentrations, [and this in turn is] because their ground is the Dharma-Sphere. [...]”.

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.
