ADHISHTHANA

Adhishthana adhishthana (Sanskrit) [from adhi over, upon + the verbal root stha to stand upon] A basis, seat, or focus of action (cf BG 3:40, 18:14). Often applied to a principle or element which inheres in another principle; i.e., the active agent working in prakriti would be adhishthnana. Also, precedent, rule, as when used as a name for one of the ten paramitas (rules of conduct).
Adhishnhana-deha or -sarira (-body) is a subtle intermediate body with which the departed is clothed after death.
