Spirituality is based on the possibility to comprehend our true nature, and thereby escape the painful cycles of life, death, evolution, and devolution, the mechanical wheel of nature. By awakening consciousness in the six intermediate states (betweens or bardos) one can transform life and death into vehicles for liberation. This is the essential point of view of the so-called "Tibetan Book of the Dead," actually named "Natural Liberation through Hearing in the Intermediate States," which begins with a prayer to the Three Buddha Bodies (Kayas). "I bow down to the spiritual teachers, [embodiment of] the Three Buddha-bodies: To the [Dharmakaya] Buddha-body of Reality, Infinite Light, Amitabha; To the [Sambhogakaya] Buddha-body of Perfect Resource, the Peaceful and Wrathful Lotus Deities; And to [Nirmanakaya] the Buddha-body of Emanation, Padmakara, protector of all beings." - The Great Liberation by Hearing in the Intermediate States (known as "The Book of the Dead") “A Bodhisattva is formed by the Holy Spirit [Nirmanakaya] of a Master dressed with the four lower bodies. This is the greatest mystery of the human personality. This is the mystery of the double human personality. This is one of the greatest mysteries of occultism. “The internal Master can send his Holy Spirit [Nirmanakaya] to the earth clothed with a Mental, Astral, Vital and physical body in order to perform an important mission. Christ, the divine redeemer of the World, after his earthly death, sent his human Bodhisattva. But the human beings knew him not.” - Samael Aun Weor, Igneous Rose This is a lecture from the free online course Death: Preparation for Transformation Course Description: Everyone will experience death, thus it is intelligent to prepare oneself for the experience. This course examines the truth of what happens when we die, and what happens in the afterlife or "between" (bardo). Most importantly, you will learn how to use today as preparation for death, and thereby transform life into a source of happiness for yourself and others. "We can learn very little from the phenomenon of birth, but from death we can learn everything." - Samael Aun Weor, The Great Rebellion
