Anger is born of desire and desire arises from thoughts. Therefore, thoughts alone are responsible for both desire and anger. Just as you cannot get cloth without thread and thread without cotton, you cannot get anger without desire and desire without thoughts.
Embodiments of Love,
In the Gita, the divine teacher has termed desire and anger as fire. There is danger of being harmed by fire even when it is some distance from you. When this is true for a fire that is burning outside then how much more careful you must be when the fire is burning fiercely in your own heart. This fire of desire and anger has an extraordinary capacity to destroy all your human qualities and to suppress the divine nature within you, leaving only the demonic qualities raging inside.
