Upadana (Sanskrit) [from upa-ada to receive] The act to taking or appropriating for oneself: in philosophy, the act of withdrawal, or receiving into the inner being, of the organs of sense from the outer world. In Buddhist literature the term is enlarged to signify the grasping at or clinging to existence caused by trishna (desire, thirst) causing bhava (new births); likewise the fourth of the twelve nidanas (bond, causes of existence), the chain of causation. In Vedantic philosophy, a cause, motive, or material cause of any kind; thus, when analyzed, the meaning is the same in Vedantic and Buddhist philosophies.
