He stayed there during the monsoon months to fulfill his purpose. Lord Balarāma and the other residents of the city, not recognizing him, offered him all honor and hospitality. KB 10.86.4 Sannyāsīs are generally meant to travel all over the country for preaching work, but during the four months of the rainy season in India, from July through October, they do not travel but take shelter in one place and remain there without moving. This nonmovement of the sannyāsī is called Cāturmāsya-vrata. When a sannyāsī stays in one place for these four months, the local inhabitants of that place take advantage of his presence to become spiritually advanced. Arjuna, in the dress of a tridaṇḍi-sannyāsī, remained in the city of Dvārakā for the four months of the rainy season, devising a plan whereby he could get Subhadrā as his wife. None of the inhabitants of Dvārakā, including Lord Balarāma, could recognize the sannyāsī to be Arjuna; therefore all of them offered their respects and obeisances to the sannyāsī without knowing the actual situation.
