That Bhakti-rasāmṛta-sindhu, the Sanskrit word . . . we have short-cut the translation, Nectar of Devotion, but the Rūpa Gosvāmī's purpose is to present the ocean of bhakti-rasa. Rasa means mellow, the juice. It is just like ocean. This ocean has limitation, but that is unlimited. Ānandāmbudhi-vardhanam (CC Antya 20.12). Caitanya Mahāprabhu said: "This ocean is increasing." Now, this material ocean, it has got limit. It cannot increase unlimitedly. That is not possible. Otherwise, how you could build these houses on the beach? No. It is ordered not to come forward beyond this line. But the spiritual bliss, that ocean is increasing. Ānandāmbudhi-vardhanam.
That is the difference between spiritual bliss and material enjoyment. Material enjoyment is limited. You cannot enjoy unlimitedly. That is not possible. Just for few seconds, for few minutes or for few hours, then it becomes disgusting. That is the material enjoyment. But the spiritual enjoyment, spiritual bliss is different. That is simply increasing. So therefore in the śāstra it is said, ramante yoginaḥ anante (CC Madhya 9.29). Those who are yogīs, bhakta-yogī, they enjoy unlimitedly. Rāmante yoginaḥ anante. And that is satyānande. That ānanda bliss is real bliss. This is artificial. This is perverted reflection.
