Selfish desire or lust is the root of all evil. The mundane desires are also the origin of all demonic qualities. These demonic or negative qualities such as an ger, greed, attachment, pride, jealousy, hatred, and fraud are born out of de sire, and are also called sin. Desire, when fulfilled, brings more desires, thereby breeding greed. The unfulfilled desires cause anger.
Anger is a temporary in sanity.
People do sinful acts when they are angry. They who act in haste under the spell of anger repent afterwards. Lust also covers Self-knowledge as the cloud covers the sun. One must learn to control desires with contentment and anger with forgiveness. They who have overcome desires have really conquered the world, and live a peaceful, healthy, and happy life.
