In 1980-81 I was living in Calcutta, which at that time was ruled by Jyoti Basu’s communist government. Even our next-door neighbor was the Polish embassy and down the street was the Soviet embassy (the temple was in the diplomatic section of town). Though Calcutta temple was far from Moscow we were part of a team that was using every possible means that we could think of to infiltrate the USSR with Krsna Consciousness.
How? Devotees like Kirtiraja Prabhu, would smuggle phone directories of major cities out of the USSR and send them to Calcutta (not sure if other temples were involved). Then under Adridharana Prabhu’s leadership we would take addresses from the phone directories and put them on envelopes containing a Russian translation of Prabhupada’s introduction to the Bhagavad-gita. Then we would take these many thousands of “time bombs” and mail them to the USSR from many different Indian cities so that the KGB and their Indian collaborators could not figure out the source. Because India and the USSR were close allies, letters from India would not be scrutinized so closely if at all, but if thousands of letters had suddenly come from a Western country suspicions would be aroused.
Admittedly we were using a scatter-gun approach and had no idea who we were sending them to. The letter could end up at the home of pious person or the head of the KGB, we just didn’t know. Nor did we know if our endeavor was having any effect.
