Harinama in a wintery Moscow, Russia (Album 65 photos)
When the Hare Krishna mantra is chanted by many men together, it is called sankirtana, and as a result of such a yajna there will be clouds in the sky (yajnad bhavati parjanyah [Bg.2.14]). In these days of drought, people can gain relief from scarcity of rain and food by the simple method of the Hare Krishna yajna. (Srimad-Bhagavatam, 9.1.17 Purport)
