A new boy raised his hand: “Why is it that one person, one soul, comes to Krsna and another doesn’t?”

Prabhupada replied with another question: “Why is one soul in the Bowery and another has come to the Krsna temple?” He paused, but no one could reply.
“Because one wants to be here and the other doesn’t,” he explained. “It is a question of free will. If we use it properly, we can go to Krsna. Otherwise we will stay down in the material world.”
