We often think of the brain as one unit, but in reality the two hemispheres operate almost independently and are only connected and coordinated through the corpus callosum. You may experience this in the first exercise, if you can concentrate and get each half of your brain to manage one distinct motion.
It is said that this kriya stimulates, balances and synchronizes the brain hemispheres, renews the cerebrospinal fluid, as well as increases gray matter, which is the part of the brain responsible for processing information, emotions, and memory.
The brain is also captain of the nervous system. These exercises, especially Exercise 6, stimulate and bring your parasympathetic and sympathetic nervous systems into rhythm and balance; they pressurize the action nervous system so you can have lightning-fast reflexes.
The mind is responsible for establishing the spiritual connection, and a healthy, balanced brain is the foundation for this. When the individual mind is refined and tunes into the universal mind, this is often referred to as prayer, meditation, simran, or naad, states of deep connection to the divine.
