Kerala Ayurveda world's oldest practiced medical system

In its essence, Ayurveda explains the laws of nature that cause health or disease. The first cause of illness is said to be the loss of faith in the Divine or experiencing a spiritual emptiness. From here illness develops due to internal conditions (e.g., foods and liquids) or external conditions (e.g., seasons, lifestyle). The main factors that cause poor health (also described as imbalance) are 1) Poor digestion 2) Weak immune systems.

When food is not properly digested it sits in the body. The nutrients are not absorbed and the food decays and forms toxins. These toxins cause most diseases in the body. Therefore, it is important to have a good digestion.

The immune system can become depleted by poor nutrition, overwork, drugs and other excesses. The finest essence of nutrition develops a life sap that protects the immune system, much like the sap of a tree heals the bruises in its bark. In addition to promoting physical health, it is the life sap that becomes transformed through meditation to produce mental peace and spiritual development. With all the immune disorders that are prevalent these days, it is even more important that persons develop their immune sap.
