The Universe is composed of the 5 elements of nature. Your body and my body are also composed of the five elements of nature. These are; Ether (Akasha), Air (Vaayu), Fire (Agni), Water (Aapa) and Earth (Pruthvi). All living and non-living creations of nature are composed of these five elements.
The 5 elements
The density of matter constitutes the earth element. The presence of water that exists in all cells constitutes water. The acid, enzymes, and other secretions that cause digestion to happen, with catabolic and anabolic processes constitutes fire. The movement of tissues and gases through the body constitutes air. The inter cellular spaces together constitute Akasha or ether.
Ayurveda is the science of balancing the 5 elements in your body and all other living organisms creatures so that they all can live in balance.
Balancing the 5 elements
Achieving this balance seems impossible due to the adversities of life, both internal and external.
Various rishis and healers, thousands of years ago, identified the five elements of nature as the source of all creation in the Universe and they described it.
Nadi Pariskha is one way of diagnosing, investigating and evaluating the misalignments in the 5 elements.
