In Hinduism, an individual is considered composed of three bodies: the karana sharira (causal body), linga sharira (subtle body) and karya sharira (gross body). These three bodies are connected, and a person functions best when they are in harmony with one another.
The linga sharira is made up of the pranamaya kosha (vital life breath), manomaya kosha (mind) and the vijnanamaya kosha (intellect). It includes the five organs of sense, the organs of action (genitals, anus, hands, legs and speech), the five vital breaths, as well as wisdom and intellect.
The three-body concept is an important core belief in Indian philosophy and in yoga. If these three bodies become unbalanced, it can cause negative effects such as disease and/or confusion.
