Age is measured by the flexibility of the spine: to stay young, stay flexible. This series works systematically from the base of the spine to the top. All 26 vertebrae receive stimulation and all the chakras receive a burst of energy. This makes it a good series to do before meditation. Many people report greater mental clarity after regular practice of this Kriya. A contributing factor is the increased circulation of the spinal fluid, which is actually linked to having a good memory.
