@ User 16618 The two principles accepted from each Sampradaya by Sri Caitanya Mahaprabhu
In the narration of Sri Navadvip-Dham-Mahatmya Srila Bhaktivinode Thakur relates the time when Sri Nityananda Prabhu took Srila Jiva Gosvami on a tour. Herein it is mentioned how Sri Chaitanya Mahaprabhu accepted two principles from each of the four sampradayas and incorporated these into His own sampradaya.
Ramanuja of the Sri-Sampradaya preached the philosophy of dasya-rasa and visishta-advaita. He was reborn as the gaura-bhakta named Ananta who lived near Vallabhacharya's house. Sri Chaitanya Mahaprabhu accepted the following two principles from the Laksmi-Sampradaya.
1.The concept of unalloyed devotion free from karma and jñana -ananya-bhakti.
2.Service to the devotees - bhakta-jana-seva.
Madhva of the Brahma-Sampradaya preached the dvaita philosophy. The following points were accepted from thissampradaya:
1.The complete defeat of the Mayavadi philosophy - Keval-advaita-nirasana.
2.The worship of the deity of Krishna and understanding it to be eternal - krsna-murti-sevana.
Vishnusvami of the Rudra-Sampradaya preached suddha-advaita philosophy. He was reborn as the Gaura-bhakta named Vallabha Bhatta who perfected his own sampradaya by Gauranga's mercy. Sri Chaitanya Mahaprabhu accepted the following from this sampradaya:
1.The sentiment of total dependence on Krishna - tadiya-sarvasva-bhava
2.The path of spontaneous devotional service - raga-marga.
Nimbarka of the Kumara-Sampradaya preached dvaita-advaita philosophy. He was reborn as the Gaura-bhakta named Keshava Kashmiri . Again, two points were accepted:
1.The need of taking exclusive shelter of Radhika - ekanta-radhikasraya.
2.The exalted mood of the gopis' love for Sri Krishna - gopi-bhava.
