Being the science of life has 2 main objectives. The 1st objective is to continue the condition of health i.e. preventive approach while the 2nd objective is to treat the disease when anyone falls ill i.e. curative approach. To attain these objectives and remain healthy , Ayurveda focuses on balancing the 3 energies (Doshas) of the body i.e. Vata, Pitta, Kapha. The basis of Ayurvedic system lies on knowing these energies(Doshas) and keep them in balanced state. So, let’s know about these 3 energies (Doshas) on brief:

Vata:
Vata is the body-energy which has the properties like dryness, lightness, coolness, mobility, subtleness etc. It is related with the movement processes occurring in our body. The main actions of Vata is related with respiration, speech, blood circulation, excretion, conduction of impulses of neurons etc. Although, 3 Doshas are present all over the body but the main site of Vata is pelvic cavity and specifically the large intestine. The predominant site of Pitta is between the stomach and duodenum.

Pitta:
Pitta is the body-energy which has properties like oily, sharpness, hotness, lightness, foul-smelling, liquidity etc. Pitta is related with the body temperature and digestion. The metabolic activity in our body is done by digestive-fire(Agni) which attains its energy from Pitta. The action of Pitta is related with digestion, vision, hunger, thirst, softness of body, glowing of skin, intelligence, hate etc. It has 5 subtypes. The predominant site of Pitta is between the stomach and duodenum.

Kapha:
Kapha is the body-energy which has the properties like coolness, bulkiness, unctuousness, heaviness, greasiness etc. Gives structure to the body and increases stability on it. Kapha lubricates the joints and oliates the body parts, helps in the proper attachment of tissues, gives weight to the body, increases sexual potency-strength-forgiveness and greedlessness.
