"When Sri Caitanya Mahaprabhu came out of the gambhira He was seeing everywhere as Vrndavana. If He would see any banyan tree, then it would appear to Him to be the same banyan tree at Vamsi vata from where Krsna called all the gopis to come for rasa dance. When He would see the ocean He would think it was the Yamuna, and those who were bathing in it to be cowherd boys and girls. This is sraddha. We have two kinds of hearts, senses, mind and intelligence, one material and one spiritual. But at the moment our transcendental nature only exists in its seed form. But if suddha sattva will come from our guru's heart then that transcendental nature will start to sprout.
