Chaitanya Mahaprabhu took two principles of the four sampradayas.This is explained in the book Sri Navadvipa Dhama Mahatmya, written by Srila Bhaktivinoda Thakura in 1890. From Ramanujacharya (Sri Sampradaya): the emphasis on devotional service (dāsya) and service to the Vaishnavas of Madhvacharya (Brahma Sampradaya): the distinction between the soul and God of Vishnuswami (Rudra Sampradaya): the feeling of exclusive belonging to Krishna (tadīyatā) From Nimbarkacharya (Kumara Samadpraya): the conyugal love towards Krishna.
