The Diamond Way is the central concept of the Vajrayana Tantras. It is a path of rapid enlightenment that emphasizes the use of skillful means, or upaya, to achieve liberation.

Padmasambhava is considered to be the founder of the Vajrayana Tantras. He was a tantric master who brought the teachings of the Vajrayana to Tibet in the 8th century.

The Vajrayana Tantras are divided into three main divisions: the Kriya Tantras, the Charya Tantras, and the Yoga Tantras. Each division has its own unique set of practices and teachings.

The goal of the Vajrayana Tantras is to achieve liberation from samsara, become a bodhisattva, and attain buddhahood. These goals are achieved through the practice of tantric methods, such as visualization, mantra recitation, and mudra.

The four main tantric practices are visualization, mantra recitation, mudra, and mandala. These practices are used to transform the mind and body into a state of purity and enlightenment.

The guru is of utmost importance in the Vajrayana Tantras. The guru is the source of all knowledge and wisdom, the one who bestows initiation, and the one who guides the disciple on the path to enlightenment.

The mandala is a sacred diagram that represents the universe. It is a tool for meditation and a place of refuge for the mind. The mandala is used to create a sacred space in which the practitioner can connect with the divine.

The dakini is a female deity who represents wisdom and compassion. She is a protector of the Dharma and a guide on the path to enlightenment. The dakini is often depicted as a beautiful and powerful woman who is dancing or flying.

The Vajrayana Tantras are a part of the Mahayana tradition of Buddhism. They are not a separate and distinct tradition from the other Buddhist traditions.

The Vajrayana Tantras are still practiced by some Buddhist schools, such as the Tibetan, Japanese, and Chinese schools. They are not only practiced by Tibetan Buddhists.
