There is a statement in the Padma Purana: "Persons who are engaged in Krsna consciousness should never be disturbed by some material gain or loss. Even if there is some material loss, one should not be perturbed, but should always think of Krsna within himself." The purport is that every conditioned soul is always absorbed in thinking of materialistic activities; he has to make himself freed from such thoughts and transfer himself completely to Krsna consciousness. As we have already explained, the basic principle of Krsna consciousness is to always think of Krsna. One should not be disturbed in material loss, but, rather, should concentrate his mind upon the lotus feet of the Lord.
A devotee should not be subjected to lamentation or illusion. There is the following statement in the Padma Purana: "Within the heart of a person who is overpowered by lamentation or anger, there is no possibility of Krsna being manifested."
