aim of yoga is the complete cessation of the mind. The body is like a container, or pot. The mind is like water. The slightest movement of the pot disturbs the stillness of the water. Therefore unless the body remains, through practice, in a state of rest, the mind within can never reach a state of tranquillity. The tranquil mind, through yogic practice, reaches the state of non-mind, which is the supreme state of samadhi, or total God Consciousness.
