What does it mean to get a tattoo in the dark?

In tantric Buddhism, Daren is an important protector and a medical god of wealth who specializes in treating diseases.

This god was originally the incarnation of Brahmanism Shiva (that is, in heaven), and was later absorbed by Buddhism and became the protector of Buddhism. Tibetan Buddhism believes that the dark sky is the anger of Piluzenafo (or Tathagata) when he fell evil. There are six-armed, four-armed and two-armed Mahabharata.

Daiwada was deeply believed by the feudal rulers of the mainland because of his characteristics as a god of war. In the Yuan Dynasty, Tibetan secrets began to spread to the mainland, and Daren first gained the worship of Kublai Khan and became the patron saint of the Mongolian army.
