When Śrī Kṛṣṇa comes to this world, there is a long separation. In Goloka Vṛndāvana, however, that kind of separation is not present. The question comes: why did Kṛṣṇa, Rāma, and Mahāprabhu manifest this type of separation in this world? The answer is that by thinking, hearing, and speaking about those pastimes of separation, one gradually attains bhakti-rasa (pure devotion) and enters the eternal pastimes of the Lord.
Navadvīpa is the place of intense separation. Here, the residents of Navadvīpa experienced the suffering of separation to the extreme extent. At the age of twenty-four, Mahāprabhu went to nirdaya- ghāta on the bank of the Gaṅgā, swam to Kaṭvā, and took sannyāsa. He left Viṣṇupriyā and Śacī-mātā at home, weeping in separation. How fortunate we are to visit these supremely holy places, where we can take the dust and hear the pastimes that were experienced there.
