Swami Mukundananda
Why is jealousy considered worse than other negative feelings like bitterness?
Jealousy hates the glory of God
Ill will is like keeping acid in your heart, and jealousy is even worse. In jealousy you are hating the success of another, which means directly hating the glory of God that permitted somebody else to succeed.
Even worse than that is jealousy. There is nothing worse than jealousy, because in jealousy you are hating the success of another. You are directly hating the glory of God.
