I visited this shop some years ago. At that time, a lady attendant informed me that she had a male friend who, in a darker period in his life, was helped very significantly and crucially by the Hare Krishna Yoga Process and / or by the Hare Krishna devotees. He might have been suicidal. She certainly made a donation and would have received a Hare Krishna book accordingly. Today, the 22nd of December 2021, I revisited this very same shop and there was a male attendant. I told him the story and asked the question: “Did that statement refer to you.” The answer was: “Yes, indeed!” With his right hand, he reached his cash register and without further talk, he handed over a donation out of the ordinary. We had a good laugh as would two transcendentalists out of danger. This proves also that one should have a designated zone of distribution and cultivate it nicely and get to know one’s customers. In this way, although a mobile business, resultant benefits will be that one does actually build “goodwill” and develops Krishna conscious business relationships. The goodwill is actually a business asset and is taken into account upon the sale of the business.
Sometimes it is actually possible in this world to swap pebbles for gold, just like when I swapped some ordinary books for a complete set of the Caitanya Caritamrta in a second hand book shop on the Sunshine Coast, Queensland, Australia.
As far as Hare Krishna preaching is concerned, there are at least two short Prabhupada quotes that sum it all up:
1) “SO THERE IS NO QUESTION OF TAKING OTHER ENGAGEMENT; DISTRIBUTION OF MY BOOKS IS THE HIGHEST KIND OF PREACHING AND THUS THE BEST ENGAGEMENT.” 740609let.NandalalDas
2) PREACHING MEANS SELLING BOOKS. 720221let.BhaktaDas
