When those devotees came to see Srila Prabhupada, Srila Prabhupada took little Saraswati, held her up over his head and said, “Do you remember me? I am your old friend.” On many occasions Srila Prabhupada indicated that these children were special. By Srila Prabhupada’s request they had been brought from higher dimensions to spread Lord Chaitanya’s mission. One of the most important things we can do is to let the children know how much Srila Prabhupada counts on them, how much he cares about them, and how important they are to him. Whatever has happened is unfortunate. Srila Prabhupada loved the children and wanted to teach them everything. Many years later I was in Dallas when Prabhupada was giving lectures about teaching the children not with a heavy hand but with love, disciplining them only with love. If you love them, they will respond, they will want to do things properly.
