In 1886 Bhaktivinoda attempted to retire from his government service and move to Vrindavan to pursue his devotional life there. However, he saw a dream in which Caitanya ordered him to go to Nabadwip instead. After some difficulty , in 1887 Bhaktivinoda was transferred to Krishnanagar, a district center twenty-five kilometers away from Nabadwip, famous as the birth place of Caitanya Mahaprabhu. Despite poor health, Bhaktivinoda finally managed to start regularly visiting Nabadwip to research places connected with Caitanya. Soon he came to a conclusion that the site purported by the local brahmanas to be Caitanya's birthplace could not possibly be genuine. Determined to find the actual place of Caitanya's pastimes but frustrated by the lack of reliable evidence and clues, one night he saw a mystical vision:
By 10 o'clock the night was very dark and cloudy. Across the Ganges in a northern direction I suddenly saw a large building flooded with golden light. I asked Kamala if he could see the building and he said that he could. But my friend Kerani Babu could see nothing. I was amazed. What could it be? In the morning I went back to the roof and looked carefully back across the Ganges. I saw that in the place where I had seen the building was a stand of palm trees. Inquiring about this area I was told that it was the remains of Lakshman Sen's fort at Ballaldighi.
Taking this as a clue, Bhaktivinoda conducted a thorough, painstaking investigation of the site, by consulting old geographical maps matched against scriptural and verbal accounts, and eventually came to a conclusion that the village of Ballaldighi was formerly known as Mayapur, confirmed in Bhakti-ratnakara as the actual birth site of Caitanya. He soon acquired a property in Surabhi-kunj near Mayapur to oversee the temple construction at Caitanya's birthplace. For this purpose he organized, via Sajjana-tosani and special festivals, as well as personal acqualitances, a massive and hugely successful fundraising effort among the people of Bengal and beyond. Noted Bengali journalist Sisir Kumar Ghosh (1840-1911) commended Bhaktivinoda for the discovery and hailed him as "the seventh goswami" – a reference to the Six Goswamis, renowned medieval Gaudiya Vaisnava ascetics and close associates of Caitanya who had authored many of the school's Th texts and discovered places of Krishna's pastimes in Vrindavan.
A main attraction in Mayapur is Srila Prabhupada's Pushpa Samadhi Mandir, a memorial to ISKCON's founder. The main shrine is surrounded by a museum depicting Srila Prabhupada's life, using fiberglass exhibits. The International Society of Krishna Consciousness is also planning to construct a garden in memory of George Harrison.
