My idea is based on the Moon 3 phases - the full moon came after 21 days. In this first submission I made only 3 but I will develop my idea in the next.
The idea here is with the Moon again, but this time in the proper way.
The symbol of the Triple Moon is a representation of the three phases of the Moon, the three phases of human life and the cycle of all things. As a symbol of the cosmic cycles it is also a representation of the process of life and death, reincarnation and rebirth.
