All to all - "For all. All for all. My books should go to all, whether they are religious or irreligious. If they keep the book, our purpose will be served." Srila Bhaktivedanta Narayana Gosvami Maharaja
"To those who are innocent, the devotee should be merciful, just to awaken their Krishna Consciousness" - Srila Prabhupada
"Oh Gurudeva, I know it is you who are distributing the books, I'm just like a toy and can't do anything. Please, let it just happen!"
One can dive into the deeper reality of transcendental book distribution through the association of devotees who are already swimming there.
Sometimes a person IS negative, and it's best to walk away.
But sometimes they can be turned; AND then it's best to stay!
