Premanand Maharaj Ji
Why should I not feel jealous of someone who is progressing?
No one is a stranger
Everyone's clay is the same and the Maker of all is the same. Bhagwan is in all, so no one is a stranger, and there is no one to be jealous of.
If your own son were in that place, would there be jealousy? There would be a blessing: may Bhagwan keep you healthy and may you rise further in the post you have reached.
