Sri Caitanya Mahaprabhu appeared in the land of Bharata-varsa, specifically in Bengal, in the district of Nadia, where Navadvipa is situated.

It is therefore to be concluded, as stated by Srila Bhaktivinoda Thakura, that within this universe, this earth is the best planet, and on this planet the land of Bharata-varsa is the best; in the land of Bharatavarsa, Bengal is still better, in Bengal the district of Nadia is still better, and in Nadia the best place is Navadvipa because Sri Caitanya Mahaprabhu appeared there to inaugurate the performance of the sacrifice of chanting the Hare Krsna maha-mantra.
