The all-merciful Supreme Lord, knowing that Kali-yuga would be very troublesome, decided to propagate devotional service. He empowered four men with devotional service and sent them into the world to preach. Ramanuja, Madhva, Vishnuswami and Nimbarka, are the names of these four great personalities. Shri Lakshmi accepted Ramanuja, Brahma accepted Madhvacarya, Rudra accepted Vishnuswami, and the Kumaras accepted Nimbarkacarya.

A Meditation by Srila Bhaktivinoda Thakur

Jahnudvipa is non-different from Bhadravana of Vraja. When will that forest be visible to my eyes? On the top of Bhisma Tila in that forest, I shall perform my worhip. In the evening, Bhisma will appear before me in his pure body, black like Krishna, wearing Tulsi-mala and marked with twelve tilak marks, constantly chanting the holy name in bliss.
