The master, it is believed, leads the student to compassion through meditation on the transitoriness of life, the relation of cause and effect of one’s actions, and the suffering of humanity. After sympathy for human suffering has been aroused, the student is taught yogic, or contemplative, exercises that help to produce inner experiences corresponding to the various stages of spiritual growth. Advancement toward enlightenment involves the identification of the initiate with deities that represent various cosmic forces. These gods are first visualized with the help of mudras (meditative gestures and postures), mantras (sacred syllables and phrases), and icons portrayed in a mandala, all of which are believed to possess the essence of the divinities to be invoked. After this visualization the initiate identifies with the divinities and finds that each in turn is shunyata (“voidness”).
According to Vajrayana traditions, the culmination of this process, called vajrasattva yoga, gives the initiate a diamond-like body beyond all duality. The four stages in the process are described in four different groups of tantras (the Kriya-tantra, Charya-tantra, Yoga-tantra, and Anuttarayoga-tantra) that are compared with the fourfold phases of courtship (the exchange of glances, a pleasing or encouraging smile, the holding of hands, and consummation in the sexual act). The first stage involves external ritual acts, and the second combines these outward acts with contemplation. The third stage involves only contemplation, and the fourth is the unification of all dualities in the sexual act, symbolically or effectively. The last stage is divided into two phases. In the first the initiate uses controlled imagination to experience the union on an ideational level. The second phase is the maithuna, or sexual coupling. Unlike the ordinary sexual act, which gives only momentary pleasure, the maithuna is considered a technique to attain enlightenment and eternal bliss because the initiate has already realized the voidness of all things, allowing perfect control over emotions and a complete absence of attachment.
These Vajrayana practices have been condemned by some Buddhists and some modern scholars as degenerate, a view ostensibly borne out by the Guhyasamaja-tantra, which states that adultery and eating of human flesh are actions of the bodhisattva. Vajrayana practices and the imagery of its texts, however, were designed to shock the complacency and self-righteousness of more traditional Buddhists. Moreover, the imagery of the texts was based on the belief that voidness alone exists and that it is beyond good or evil in the usual sense. The imagery is also based on the belief that any acts that bring about this realization are acts that benefit the practitioner and all sentient beings. Vajrayana literature
The tantras, the genre of texts unique to the Vajrayana tradition, are written in a highly figurative and symbolic language to enable individual spiritual development. Because of this symbolic character, the tantras have usually been kept secret, and a literalist interpretation of such texts has usually failed to make any sense out of them.
The Guhyasamaja-tantra (“Treatise on the Sum Total of Mysteries”), also called the Tathagataguhyaka (“The Mystery of Tathagatahood [Buddhahood]”), is the earliest-known tantra and is traditionally ascribed to Asanga (c. 4th century ce), the renowned Indian scholar and propounder of the Yogachara philosophy. Unlike most tantras, which do not explain the technical or symbolic terms that they employ, the Guhyasamaja-tantra devotes a very long chapter to the elucidation of these terms.
An important feature of all tantras is a polarity symbolism, which appears on the physical level as the union of male and female, on the ethical level as the union of beneficial activity and an appreciation of what there is as it is, and on the philosophical level as the synthesis of absolute reality and absolute compassion. The richness of this symbolism is apparent in the opening of the Guhyasamaja, where the absolute, which is depicted as a polarity, manifests itself in various mandalas (circular diagrams that have both a psychological and a cosmic reference), each related to one of the celestial buddhas—Akshobhya, Vairochana, Ratnasambhava, Amitabha, and Amoghasiddhi. Each of these buddhas again represents a polarity that is often portrayed in iconographic works through their union with female consorts.
The tantras may emphasize either “beneficial activity” or “appreciative awareness” or their “unity,” and, therefore, Tantric literature has been divided into the so-called Father Tantra (emphasizing activity), the Mother Tantra (emphasizing appreciation), and the Nondual Tantra (dealing with both aspects unitively). The original Sanskrit versions of most of these works have been lost, but their influence is noticeable in works such as Jnanasiddhi (“Attainment of Knowledge”) by the great Vajrayana teacher Indrabhuti (c. 687–717), Prajnopayavinishchayasiddhi (“The Realization of the Certitude of Appreciative Awareness and Ethical Action”) by the 8th-century writer Anangavajra, and the songs of the 84 mahasiddhas (“masters of miraculous powers,” who were considered to have attained the Vajrayana goal). One of the last Sanskrit works to have been written in Central Asia was the Kalachakra-tantra (“Wheel of Time”), which probably entered India in 966 ce. It taught that the Adi-Buddha—primeval Buddhahood—manifested itself as a continuum of time (kala) and space (chakra). Vajrayana Schools in Tibet
When Tibet was converted to Buddhism (7th to 11th century), the most dynamic form in India was Vajrayana; thus, it was this tradition that became established in Tibet. Little is known about the early stages of the conversion (7th to 9th century), however, and the role of Vajrayana in the conversion before the 11th century, when several identifiable schools emerged, remains unclear.

Rnying-ma-pa
Among the Vajrayana schools of Tibet and neighbouring regions, the Rnying-ma-pa claims to preserve most purely the teachings of Padmasambhava, the 8th-century Indian miracle worker who helped convert Tibet by using his magical prowess, it is believed, to quell the local demons. The Rnying-ma-pa makes fuller use than any other school of the “discovered” texts of Padmasambhava. These texts are believed to have been hidden since the early 9th century, when persecution began in Tibet, and their discovery began in the 11th century and continued until the late 20th century. Their importance to this school is reinforced by the Rnying-ma-pa notion that “hidden treasure” has strong spiritual and historical overtones.
The Rnying-ma-pa order divides Buddhist teaching into nine progressively superior groups and subdivides the tantras in a manner different from that of other Vajrayana schools. The six groups of tantras are: Kriya, or ritual; Upayoga, which involves the convergence of the two truths and meditation on the pentad of buddhas; Yoga, which involves the evocation of the god, the identification of the self with the god, and meditation on the mandala; Mahayoga, which involves meditation on the factors of human consciousness (skandhas) as divine forms; Anuyoga, which involves secret initiation into the presence of the god and his consort and meditation on “voidness” in order to destroy the illusory nature of things; and Atiyoga, which involves meditation on the union of the god and his consort, leading to the experience of bliss. Members of the order believe that those initiated into the Kriya can attain Buddhahood after seven lives, the Upayoga after five lives, the Yoga after three lives, the Mahayoga in the next existence, the Anuyoga at death, and the Atiyoga in the present existence.
