It is essential to know that our egos are ill and are dysfunctional no matter how they express ego. When we are seduced in ego we nor our ego often do not recognize (blind spot) we are in pain that can lead to suffering. The ego is incapable of seeing the negative it projects on others. The ego cannot distinguish between a situation and its awareness of and reaction to any given situation.
Emoted anger or resentment fuels the ego by increasing duality and separation often producing an illusion of being right. Cleverness from the ego separates; intelligence from the heart is inclusive.
