Japanese Zen is derived from the Japanese pronunciation of the Middle Chinese word 禪 (Chan) which traces its roots to the Indian practice of dhyāna ("meditation"). Buddhism was introduced to China in the first century CE. According to tradition, Chan was introduced around 500 CE by Bodhidharma, an Indian monk teaching dhyāna. He was the 28th Indian patriarch of Zen and the first Chinese patriarch. Buddhism was introduced in Japan in the 8th century CE during the Nara period (710-794) and the Heian period (794–1185). Zen was not introduced as a separate school in Japan until the 12th century during the Kamakura
Shambhala Buddhism the teachings of the Shambhala lineage derive from the "Epic of Gesar" as propagated by Mipham the Great. Trungpa Rinpoche was deeply influenced by his friend Shunryu Suzuki Roshi, a Japanese Zen master who was one of the first accomplished teachers to present dharma to Westerners. As a result of this influence, certain attributes of form in Shambhala Buddhism are derived from Zen, rather than Tibetan Buddhism. The shrine rooms in Shambhala Buddhism, reflecting the Zen aesthetic of "Kanso" (簡素) or simplicity, tend to be sparsely furnished and decorated, whereas traditional Tibetan Buddhist shrine rooms are elaborate, ornate, and colorful.
