Sannyasi should go on preaching, preaching, preaching, preaching. Practically, I was sitting here in Vrndavana, in Radha-Damodara temple. So at the age of seventy years, nobody goes out. At least from Vrndavana nobody goes at the age of seventy years. But Krsna asked me. I thought that “I must go. Guru Maharaja wanted it, Caitanya Mahaprabhu… Let me try.” So if I had not gone, then this institution would not have developed. So this is practical. mahat-vicalanam (SB 10.8.4). Mahatma, they must move. So when there is absolute necessity they may stay. Otherwise, they must move. Move on, move on, move on, move on, move on. No staying. That is principle. No staying. I am this old age, I cannot move. Still I am traveling all over the world. I am simply interested that whatever I have done, it may not be vanquished in my absence. Let me go and encourage them. Otherwise, I have no capacity to move now. But still I am moving, only for this purpose. grhinam dina-cetasam (SB 10.8.4). So a sannyasi must move. A sannyasi must not stay anywhere more than three days. That is the principle. Besides that, a temple is nirguna. A sannyasi is forbidden to stay anywhere else, but in a temple he can stay for more than three days, provided there is business. Otherwise, there is no necessity.
