How did Buddhism develop into tantric Tibetan culture? In fact, it is Buddhism-mobile phone.

Regarding these historical materials, we can simply say that there are no human beings in Tibet. At the beginning, the monkey incarnated by Guanyin Bodhisattva and the woman incarnated by Tara combined to give birth to Tibetans. So Tibet is the land of avalokitesvara, and Tibetans are the people of avalokitesvara. Many Tibetans have been chanting the six-character Daming mantra of Guanyin all their lives. After that, there was no Buddhism in the snowy area, but from generation to generation, different kings and different wishes gradually invited Buddhism. Probably at the beginning, some Buddhist scriptures were lost from somewhere in the first palace. At that time, everyone didn't know much about it, but it was a unique fate in the snowy area. Later, he came to Songtsan Gampo to marry Nepalese Princess White Tara (incarnation) and Tang Dynasty Princess Wencheng (incarnation of Green Mother) to benefit all beings in the snowy area. The Tibetan area entered the only twelve-year-old and eight-year-old Buddha statues personally blessed by Sakyamuni Buddha when he was alive, and practiced Buddhism. Later, during the ode to Akamatsu, the French king sent people to India to practice Buddhism, welcomed Indian masters such as Lotus Peanut and Bodhisattva to Tibet, sorted out and translated Buddhist scriptures, and established the first temple in Tibetan history-Samye Temple. Specifically, you can see the book "History of Ancient Buddhism in Tibet" by King Dunzhu II. Buddhism has penetrated into the life of Tibetans, and all kinds of habits of accumulating virtue and doing good are in the Tibetan cultural tradition.
