Modadrumadvipa is known as Mamgachi. Lord Nityananda went to Mamgachi village along with all the devotees. Lord Nityananda said, “This Modadrumadvipa is non-different from Ayodhya. During the previous kalpa when Lord Rama went to live in the forest, He came to this place along with Lakshmana and Sita-devi. They built a cottage under a great banyan tree and stayed there happily for a few days. Upon seeing the effulgence of Navadvipa Sri Raghunandana Ramacandra smiled. He looked very beautiful in His nava- durva-dalasyama form. Rajiva-locana (the lotuseyed Lord) was holding a bow and arrows and was dressed like an ascetic brahmacari with matted locks on His head. Everyone’s mind was attracted just by seeing Him. When Sita-devi saw the smiling face of Lord Ramacandra, She asked, ‘What is the cause of Your smiling?’ Lord Ramacandra replied, ‘O Sita, daughter of King Janaka! Please listen to this very confidential story. In the future when the most blessed Kali-yuga comes, I will appear here in Nadia in a golden yellow form. I will take birth as Gauranga from the womb of Saci in the house of Jagannatha Misra, as their son. All those fortunate people who see My childhood pastimes will receive transcendental love. At that time I will enjoy vidya-rasa (the pastime of education). I will reveal the glories of Sri Nama (the holy name). After that I will accept the order of sannyasa and go to Nilacala. My mother will cry, placing her daughter-in-law on her lap.’ Hearing this Sita-devi said, ‘O, Rajiva-locana! Why will You make Your mother cry? Why will You accept sannyasa leaving aside Your wife? I do not understand what pleasure You will receive by giving suffering to Your wife.’ Sri Ramacandra replied, ‘My darling! Although You know everything, You are asking a seemingly ignorant question. One can relish prema-bhakti unto Me in two different ways. One can experience the pleasure of premabhakti in union with Me known as sambhoga. And the pleasure My devotees experience by being separated from Me is known as vipralambha. My devotees always desire to be united with Me, but by My mercy they also achieve vipralambha-bhava. In vipralambha, whatever suffering one undergoes is for Me only. Whatever suffering a devotee goes through in vipralambha, due to Me, he accepts with great relish. For at the end of vipralambha when sambhoga is attained, My devotee enjoys a million times greater pleasure. In this way separation from Me is also the cause of pleasure, therefore My devotees accept this state of separation. 

This has been explained in the Vedas. During the time of Mygaurangaavatara, mother Kausalya will appear as Saci-devi who is described in the Vedas as Aditi. During that time You will serve Me as Vishnupriya. In the future, feeling separation from You, I will worship You in Your golden deity form in Ayodhya-nagara. In return You will worship My golden gauranga-murti form in Nadia-nagara. Sita-devi! This is a very confidential topic. At present this subject will not be revealed to the people in general. This Navadvipa is very dear to Me. Even other dhamas like Ayodhya are not equal to this dhama. This Rama-vata tree, of which We have taken shelter, will disappear from the vision of the people when Kali-yuga begins but will remain here in an invisible form.’” Lord Nityananda continued, “In this way Rama, Sita and Lakshmana stayed here in Modadrumadvipa for a few days and then went to Dandaka forest to perform Their duty. Here you can see the kutira of Lord Ramacandra.”
