The fuel of the operation of the individual existence and egocentric identity is desire. Everything that comes into existence is born of desire.
You appear out of the absolute and integrate into existence as an individual and separate identity. Yet you yearn to feel the all-inclusive connection and acceptance of the absolute. Humans characterize this experience as love, and the dynamic of desire in humans manifests as the yearning for love. This is both a conscious and unconscious process.
This yearning for love and the extent to which the individual perceives that this love is given or withheld in the flow of their personal experience produces the effect of desire. This is a universal energy.
