In Advayavada Buddhism we say that karma is basically and simply the operation of incessant pratityasamutpada (interdependent origination) at the sentient level (pratityasamutpada, that is, as in Madhyamaka philosophy, where ‘all causes are effects and all effects are causes’). Our own karma is the everchanging knotlet of biopsychosocial events in which we are personally embedded. These events include traditionally the consequences of one’s actions (the kamma niyama), the laws of heredity (the bija niyama), the environment (the utu niyama), the will of mind (the citta niyama) and Nature’s tendency to perfect (the dhamma niyama).
