“If somehow all the books in the world were destroyed, leaving only Srimad-Bhagavatam and Sri Caitanya-caritamrta, the people of this world could still achieve the ultimate goal of life. Even if Srimad-Bhagavatam were lost, leaving only Sri Caitanya-caritamrta, there would be no loss to humanity, for whatever has not been revealed in the Bhagavatam is found in Sri Caitanya-caritamrta. The Absolute Truth is Sri Caitanya Mahaprabhu, the combined form of Radha and Krsna. Sri Caitanya-caritamrta is His sound incarnation, within which is found the divine mystery of Radharani’s divine status and glories. Therefore, can there be any doubt concerning the supreme status of this transcendental literature?”
 
As he stood up after ending a lecture in Munger, an earth tremor caused mild flooding of the adjacent Ganga. The water soon receded, after which Srila Sarasvati Thakura said:
 
“In due course maha-pralaya (devastating floods) will inundate the entire universe. If you attempt to survive by swimming in that deluge, then do not neglect to take hold of Bhagavad-gita, Srimad-Bhagavatam, and Sri Caitanya-caritamrta. Or if you cannot hold all three, then release Bhagavad-gita. If necessary you may also relinquish Srimad-Bhagavatam, but under no circumstances release your hold on Sri Caitanya-caritamrta, for if this one book remains then the flood can do no actual damage, because after it has subsided, the message of sastra can be revived from Sri Caitanya-caritamrta alone, it being the essence of all sastra.”
