Please help me to explain these two temple tricks by netizens who know Buddhist culture.

Hello! I don't know the first one, and the second one is the reincarnation of Thangka in Tibet. Details are as follows:

The six maps in this special Karma Wheel have always been used as teaching tools to explain the basic world outlook of Tibetan Buddhism.

The whole picture is a big round wheel bitten by a huge Yamaraja, symbolizing the six ways that all beings want to be reincarnated, with no period.

The six divisions in The Wheel of Causality Diagram (1) are the demonstration diagrams of the samsara theory taught by Sakyamuni Buddha (upper right of the diagram).

(2) Through the practice of Buddhism, the six sentient beings finally got rid of reincarnation and rose to the pure land of Buddhism (figure left).

(3) The innermost circle is chicken, snake and pig, representing greed, greed and ignorance.

(4) The second circle is divided into black and white semi-rings, representing (black) bad karma and (white) good karma.

(5) The third circle is about Heaven, Humanity and Asura's Three Good Ways; There are three kinds of evil ways: hell, hungry ghost and animal way.

(6) The fourth circle is twelve karma: from ignorance, knowing karma, knowing karma's name, six entering karma, touching karma, being loved by karma, taking karma, being born by karma, and dying of old age.

(7) The Buddha became a Buddha by practicing and observing the twelve causes. Here, different images are used as symbols.
