Upādāna, the Sanskrit and Pāli word for "attachment" or "grasping", has the following meanings:
Upādāna translated from Sanskrit means clinging or grasping and refers to the ninth link in the twelve-linked chain of Dependent Origination (Pratītysamutpāda).
Upādāna and Tṛṣṇā are seen as the two primary causes of suffering (Duḥkha) in Saṃsāra.
Upādāna (Clinging) is dependent on Tṛṣṇā (Craving) as a condition before it can exist.
Upādāna (Clinging) is also the prevailing condition for the next condition in the chain, Becoming (Bhava).
