Sahakāri Kāraṇam — The Instrumental Cause
Sahakāri kāraṇam (Sanskrit: saha = together + kāra = doing/causing + kāraṇam = cause; 'co-cause' or 'assisting cause') refers to the auxiliary conditions and instruments that support the primary causes (upadāna and nimitta) in bringing about an effect. They are necessary but not themselves the primary movers.
Classical Analogies:
- Potter (nimitta) + clay (upadāna) + potter's wheel, water, fire (sahakāri) → pot
- Spider (nimitta+upadāna) + space around it (sahakāri) → web
In Vedāntic Context: In discussions of creation, the sahakāri includes time (kāla), space (deśa), and the karma of individual souls — which constrain when and how Bhagavān's creation unfolds. 'Bhagavān creates as He wills, but the jīvātmā's accumulated karma (sahakāri) determines the specific form and conditions of each birth.'
Sahakāri in Spiritual Practice: In the context of prapatti, the three causes framework appears in understanding why Āchārya-kṛpā and Bhāgavata-satsaṅga (association with devotees) are sahakāri — they are not the liberating cause itself (which is Bhagavān's grace alone) but they are the indispensable conditions that prepare the aspirant and allow Bhagavān's grace to act fully.
