What is the difference between soul and ego?
The soul is a true reflection of the Spirit, and is therefore pure. When the soul becomes identified with the body, it converts itself into the ego. In a worldly person, the ego is the guiding principle of all thoughts, feelings, and aspirations.
One must learn to differentiate between material desires and soul desires. The pure soul loves the wisdom and bliss experienced in the union with the absolute, omnipresent, omniscient One.
The ego loves name, fame, pride, greed, body-attachment, and all perishable qualities. When the ego succeeds in persuading the mind to like the perishable comforts of the body, the mind becomes spiritually blind and no longer prefers the imperishable joys of the soul resting in omnipresence.
