Shambhala TrainingIn 1976,at a party
[4], Trungpa Rinpoche began giving teachings, some of which were gathered and presented as
Shambhala Training,
[5] inspired by his vision (see
terma) of the legendary Kingdom of Shambhala. Shambhalian practices focus on using mindfulness/awareness meditation as a means of connecting with one's basic sanity and using that insight as inspiration for one's encounter with the world. The Shambhala of Chögyam Trungpa is essentially a
secular approach to meditation, with roots in Buddhism as well as in other traditions, but accessible to individuals of any, or no religion. The greater social vision of Shambhala is that it is possible, moment by moment, for individuals to establish
enlightened society.
