First objective of Ayurveda is to strive for Dharma, Artha, Kama and Moksha. Dharma means to observe social and moral rules. Duties towards self and others. Artha means understanding our surrounding by sense-organs of body and thinking over it. Kama means desire of various kinds.
Moksha means salvation. To break the cycle of birth-death and rebirth. Think about who am I? It aims at maintenance of metabolic equilibrium.
For achieving above aims, Ayurveda insists that every Person should observe Dincharya means Daily Routine, Rutucharya means Seasonal Routine, and Sadvritta means Ethical Routine. Ayurveda gives stress on observing Aahara - Diet, Nidra - Sleep and Bramhacharya i. e. Avoidance of mental or sexual intercourse without purpose.
All individuals does not respond to the same stimulus alike. There are variations in the reactions and this is due to different constitutions. This is classified mainly in three categories.
Basic constitution is decided at the time of conception. Constitution means Prakruti. Its meaning is nature, creativity or the first creation. The first expression of the basic five elements is the constitution. There are seven types of Prakruti. It means each individual is different and this Prakruti plays a vital role in diagnosis of diseases and treatment of diseases according to Ayurveda. Different Prakruti are formed from different combinations of Dosha (the humors). Then are 3 different humors (Vatta, pitta, Kapha ) that regulate the different functions of the body. Vatta being derived from the combination of ether and Air regulates principally all the body movements all from macro to micro level of movements. Pitta dosha derived from the combination of fire and water is related to production of heat, digestive juices (also called Agni). Kapha dosha is derived from the combination of water and earth is principle of stability.
Throughout life there is a constant interaction between the internal and external environment. A basic principle of healing in Ayurveda holds that one may create balance in the internal forces working in the individual by altering diet and habits or living to counteract changes in his/her external environment. Equilibrium of three Doshas is disturbed by slightest stimulation from outside or within the body. To be healthy, equilibrium of three Doshas, seven Dhatus and three Malas is very essential.
Unhealthy habits, Lifestyle, Lack of exercise, stress, junk nutrition causes alteration of metabolism producing Ama ( i.e. the in-digested food remains ) which block different body channels, also called the srotas and develop disease in the body. Now, the principle of treatment according to Ayurveda depends upon the prakruti of the person, dosha which are fluctuated, after considering, the above points treatment in approved.
