Eight metals like skin, blood etc. form the body. They are represented here as the wheels of the chariot – this body is an eight-wheeled chariot. Prana is the only axis of this. In the folk, the wheels of the chariot surround the axis. The prana-like axis comes out of one wheel and enters the other. That soul enters all beings from one part of itself and arises as a soul. The second part of it becomes the flag of unlimited Brahman i.e. the universe. (22)
