As per [https://en.wikipedia.org/wiki/Ayurveda Ayurveda], the functioning of universe depends upon ''agni'' and ''soma'' which symbolize sources of hot and cold energy. ''Uttarayana'' (northward sojourn of sun) and ''dakshinayana'' (southward sojourn of sun) are together responsible for maintaining homeostasis on this planet. This homeostasis is also mirrored in the individual through the concept of ''loka purusha samanya siddhantha'' (that the individual is a microcosm of the universe, the macrocosm). The ''purusha'' (individual human being) imbibes this energy and confines it in the ''sharira'' (body) as ''pitta''. This ''pitta'' controls, or rather regulates, the ''ushmanattva'' (core body temperature) of the body ([[Charaka Samhita]] [[Sutra Sthana]] 12/11). It is responsible for all the metabolic processes at the cellular level and digestion at the level of the gut. ''Pitta'' is the contributor of ''ushna guna'' (warmth) to the body. The stimulator (''preraka'') of ''pitta'' is ''vata'' (the accelator-''sameerano agnehe'' ([[Charaka Samhita]] [[Sutra Sthana]] 12). ''Vata'', in association with ''pitta'' and ''kapha'', maintains the normal core body temperature by controlling the heat regulating system and balancing the ''sheeta'' and ''ushna guna''. | As per [https://en.wikipedia.org/wiki/Ayurveda Ayurveda], the functioning of universe depends upon ''agni'' and ''soma'' which symbolize sources of hot and cold energy.
