Jealousy not only makes us unhappy, but it also has more negative results. Saint Thirumoolar, says that we should not harbour envious thoughts in our minds. If we are envious, the beneficial effects of our good deeds get reduced.

In other words, our punyas are depleted. Moreover, a portion of the sins of the person who is the object of our envy, gets transferred to us. So now we not only have a situation wherein some of our punyas are lost, but also one in which someone else's sins are transferred to us. Is such a state desirable?

This double punishment can be avoided, if we are not jealous of anyone.
