Bhaktivinoda was transferred to Krishnanagar, a district centre away from Nabadwip, famous as the birthplace of Caitanya Mahaprabhu. Despite poor health, Bhaktivinoda began to regularly visit 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 past but frustrated by the lack of reliable evidence and clues, one night he saw a mystical vision: Taking this as a clue, Bhaktivinoda conducted an investigation of the site by consulting old maps matched against scriptural and verbal accounts. He concluded that the village of Ballaldighi was formerly known as Mayapur, confirmed in Bhakti-ratnakara as the 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 organised, via Sajjana-tosani and special festivals, as well as personal acquaintances, a hugely successful fundraising effort. 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 Vaishnava ascetics and close associates of Caitanya who had authored many of the school's theological texts and discovered places of Krishna's pastimes in Vrindavan. Nama-hatta Kedarnath started a travelling preaching program in Bengali and Orissan villages that he called nama-hatta, or "the market-place of the name [of Krishna]". Modelled after the circuit court system, his nama-hatta groups included kirtana parties, distribution of prasada (food offered to Krishna), and lecturers on the teachings of Gaudiya Vaishnavism, travelling from village to village as far as Vrindavan in an organised and systematic way. The program was a big success, widely popularising the teachings of Caitanya among the masses as well as attracting a following of high-class patrons. By the beginning of the 20th century Bhaktivinoda had established over five hundred nama-hattas across Bengal. Opposing Vaishnava heterodoxy Prior to Bhaktivinoda's literary and preaching endeavours, an organised Gaudiya Vaishnava sampradaya (lineage) was virtually nonexistent, as was a single, overarching Gaudiya Vaishnava canon in a codified form. In the absence of such theological and organisational commonality, claims of affiliation with Gaudiya Vaishnavism by individuals and groups were either tenuous, superficial, or unverifiable. Bhaktivinoda Thakur attempted to restore the once strong and unified Caitanya's movement from the motley assortment of sects that it came to be
