Buddhist Tantra is also known as Vajrayana Tantra. According to tradition and lineage of Buddhist Tantra it is the path to enlightenment, which is achieved through use of Tantra techniques that are practical aids to spiritual development. The esoteric transmission of Vajrayana knowledge is the part of this spiritual practice. The earlier schools of Buddhist doctrine might provide way to achieve Nirvana over the course of many lifecycles but the Tantric Buddhism are meant for the purpose of full enlightenment or Buddha hood which is possible in a shorter time i.e. in the single lifetime. Vajrayana methods do not claim that the Theraveda or Mahayana practices to be invalid. Infact the teachings from other Buddhist practice this act as the foundation of Tantric Buddhism.

The Mahayana and Therveda paths are said to be the paths of enlightenment in their own right. The teachings from those doctrine aims towards the Vajrayana method. The Vajrayana evolved from the Mahayana Buddhism, which employs special means to accelerate the process of awakening. The goal of Tantric Buddhism is to become a Buddha by following Bodhisattva path. The distinction between different methods of Buddhism is not always very rigid. The Tantra section sometimes includes material from Tibetan tradition as well as Pali sutra. The Buddhist Tantra evolved in ancient Bengal.

The main Tantric practices in Buddhism can be summarized in the four purities like seeing one`s body in the body of deity, seeing one`s environment as the pure land or Mandala of the deity, perceiving one`s enjoyments as the bliss of the deity and considering as free from any attachment and performing one`s actions only for the benefits of the others.

The Tantric Buddhism has three methods viz Guru yoga, deity yoga and death yoga.
Guru Yoga : It is the tantric devotional process where the practitioner unites their mind stream with the mind stream of the guru. The process of Guru Yoga often involves the visualization of a refuge tree as an invocation of the lineage.

Deity yoga: Deity yoga employs high-refined techniques of imagination and visualization in order to self identify with the divine form and sacred qualities of a particular deity as the union of skill and wisdom. The deity is represented as Murti, Tangka or Mandala. Visualization, invocation and evocation are important parts of Deity Yoga. Mandalas are sacred enclosures and uncontainable essence of a Yidam.

Death Yoga : It is the another important aspect of Tantra techniques. The death Yoga is practiced during the life. It is the meditative practice that helps to prepare the practitioner for what they need to do at the time of their death. At the time of death the mind is in a clear state that can achieve enlightenment, when used very skillfully. During the time of death, rebirth and in between state the mind is in a very subtle state and an advanced practitioner can use these natural states to make significant progress in the spiritual path.

Love and Passion are important part of Tantric Buddhism. Buddhist iconographers use sexual polarity to symbolize the twin concepts of insight and compassion. All goddesses are the symbols of the insight and the gods represent the compassion. This union is represented visually by showing two deities in the sexual congress. In Sanskrit such images are called Yuganaddha (pair united). This sexual metaphor is also used to denote the highest stage of Yoga in which everything is free from polarity or any discrimination. The Buddhist couples of Tantric iconography celebrate the deep harmony of sexes, which ultimately devoted to the realization of the ultimate truth.
