Jananivas: Every evening I would take a pot with coals, charcoal and frankincense and go into Prabhupada's room after first offering it to the deities. I would make the frankincense into powder to give it much more smoke.
Prabhupada loved it and said, “Give me more, give more.” It would become very thick so I asked, “Shall I open the windows and doors Prabhupada?” “No, no, it's okay.” “Shall I turn on the fan?” Again he said, “No” because he liked it. In Bengal, at least, if you put smoke in the room, turn the lights off, open the doors and the windows and when you put the fan on, immediately all of the mosquitoes, “whoosh”, fly out of the room. But Prabhupada always said, “No, keep the windows and doors closed.”
But the last time when Prabhupada was in Mayapur in 1977, I took the smoke into Prabhupada's room starting under his desk and then all around the rooms. I was sitting by Prabhupada’s side as he was chanting japa very softly: “Hare Krishna Hare Krishna Krishna Krishna”. You could hear Prabhupada’s beads clicking with the each mantra as the beads rattled in his bead bag. Then he opened his eyes, looked up at me and said, “This smoke gives such an atmosphere of spiritual understanding. This is so nice, so nice, so nice. Hare Krishna Hare Krishna Krishna Krishna…”
After all these years I finally understood that the smoke had nothing to do with the mosquitoes. [laughs] Prabhupada just allowed it because of the spiritual atmosphere it created. We thought it was to get rid of the mosquitoes.
