Ego, Error and Desire

Q: It is said that with the presence of ego one cannot have love, joy, happiness etc. in Yoga. But I had these experiences in the past. What then about my ego?

It had been subdued, by a knowledge from above and a will in the mind. It was still there, but its movements and their power were too small and the movement above too large for that to interfere except by bringing in small movements of error and desire. Error and desire are not the same thing. Error is of the mind, desire is of the vital.

– Sri Aurobindo
