If a passion embraces you, you should remember that this passionate desire is not a part of your soul, but a dark covering which shuts out the true qualities of your soul.
You should be a lantern for yourself. Draw close to the light within you and seek no other shelter.
— Buddhist Wisdom
A person's soul may be compared to a transparent ball which is lit from the inside with its own light. This flame is not only the source of all light and truth, but it illuminates everything around you. In this state, the soul is free and happy. Only if it becomes addicted to anything outside you will it become troubled, darkened, and impenetrable. Distractions obstruct the light which shows you the way.
— Marcus Aurelius
The soul is a mirror in which you can see the reflection of divine intellect.
— John Ruskin
As soon as you feel passion, try to feel in yourself the understanding of your divine nature. As soon as you perceive that your divine nature is inactive and that you are possessed by passions, fight with these passions.
