Kṛṣṇa is the ocean of all pleasure, reservoir of all pleasure. There are different types of pleasure. Just like pleasure like master and the servant. The master is also pleased by the service of the servant, and the servant is pleased by rendering service to the master. This is taste.
So this is simultaneously one and different. This acintya-bhedābheda-tattva you'll find everywhere in Vaiṣṇava philosophy. Similarly, here the author of Caitanya-caritāmṛta is trying to explain that pañca-tattva eka-vastu, they are one Kṛṣṇa, but āsvāda, taste... Akhila-rasāmṛta-sindhu. Kṛṣṇa is the ocean of all pleasure, reservoir of all pleasure. There are different types of pleasure. Just like pleasure like master and the servant. The master is also pleased by the service of the servant, and the servant is pleased by rendering service to the master. This is taste. Husband and wife: Husband is pleased having a wife, wife is pleased having... These are the different tastes: between master and servant, between friend and friend, between father and son, mother and son, between the lover and the beloved. These are different tastes. So this taste is required, transcendental mellow. The Māyāvādī philosophers, they cannot understand this taste. They think everything is one. And in the material world also, we accept, "Variety is the mother of enjoyment." Without varieties, although everything is spiritual... In Vṛndāvana everything is spiritual. Gauḍa-maṇḍala-bhūmi, yebā jāne cintāmaṇi. Just like this place, Gauḍa-maṇḍala-bhūmi, Śrī Caitanya Mahāprabhu's place of pastimes, and the Vṛndāvana-dhāma, the place of pastimes of Lord Kṛṣṇa, they are one and the same. Therefore Narottama dāsa Ṭhākura says that gauḍa-maṇḍala-bhūmi, yebā jāne cintāmaṇi, tā 'ra haya vraja-bhūmi vāsa. These are the theses given by great ācāryas.
