If one loses faith in the process of chanting of the Holy Name of the Lord, the power of the Holy Name of the Lord, then they have to cry. Tears should come from their eyes. They should actually be praying and crying to Krishna "Please do whatever is necessary to restore my faith in the Holy Name of the Lord." These tears are the price one has to pay to stay under the protection of this internal potency. Without these tears in one's eyes and a further desire to pray for the Lord's protection, Prabhupada says that Maya can take you at any moment.
