The root-cause of all discontentment is envy. You can be self-satisfied only when envy is eradicated from your heart. The contented individual enjoys peaceful living. How does envy arise? Discontent over what one lacks gives birth to envy. For example, when you compare yourself with those who are better off, or hold higher office, or score higher marks, or are more good looking, you suffer from a consciousness of your own inferiority! It is a crime to entertain envy within. To get rid of this evil quality, look at those who are worse off than you. For instance, when you look at those who got lower marks, you can derive comfort from the fact that you have done better than them! Hence, get rid of envy by comparing yourself with those who are worse off. In due course you must develop a sense of equal-mindedness towards those who are better off and those who are worse. Such equal-mindedness is a Divine quality.
