Where there is light, there is bound to be its shadow around. Likewise, good people are bound to face difficulties. But those difficulties will enhance the goodness in them. Pleasure and pain, good and bad co-exist, none can separate them. You cannot find pleasure or pain, good or bad to the exclusion of the other.
Pleasures result when difficulties fructify.
When Chaitanya was singing the glory of Krishna in the streets, some evil-minded people snatched away the cymbals from his hands. But he was least perturbed. He continued to sing the glory of Krishna with firm faith and devotion. Seeing Chaitanya, the children would get inspired and they would join him in singing the divine name. Chaitanya used to make children sit around him and impart sacred teachings to them.
