The Acintya bedha-abedha tattva of LCM

[Venugopal & Padmini]

Caitanya's philosophy of acintya-bhedābheda-tattva completed the progression to devotional theism. Rāmānuja had agreed with Śaṅkara that the Absolute is one only, but he had disagreed by affirming individual variety within that oneness. Madhva had underscored the eternal duality of the Supreme and the Jīva: he had maintained that this duality endures even after liberation. Caitanya, in turn, specified that the Supreme and the jīvas are "inconceivably, simultaneously one and different" (acintya-bheda-abheda). He strongly opposed Śaṅkara's philosophy for its defiance of Vyāsadeva's siddhānta.
