The program of the ego is centered in domination, manipulation and control. It is not capable of doing anything outside of attempting to attain its personal agendas. Desire is born out of unmet needs and those desires to meet the needs drive the personality to disregard everything that is not in alignment with its quest.
It is all done from a place of pain. The unconscious need for love, money, power, control, satisfaction, etc… is what keeps us trapped in cycles of pain and suffering.
