Who is the six-armed red face of Tibet's protector?

The six-armed red face of the Tibetan dharma protector is the six-armed black Mahagara. Daiwada (Sanskrit: Mahakara, Tibetan: Gongpo) is also translated into Daiwada, Dashi, Daiwada or Daiwada, or directly transliterated into Mahagalo (a name that often appears in Buddhist scriptures), Mahagoro, Mahagalo and other names. Originally, it was a transformation of Brahman Shiva (Sanskrit: Shiva, also known as Sanskrit: Mahesvara), and this deity was absorbed by Buddhism and became the protector of Buddhism, especially tantric Buddhism. Tibetan Buddhism believes that the dark sky is the anger when the Buddha (Vairocana in Sanskrit, namparnangzhe in Tibetan, or Tathagata) falls.
