Our many psychological "I's" or "ego's" is not one but they're legion if we look within ourselves. Many competing desires that wants to become the king of our body, that wants to rule our kingdom. They are the demons that we have inside. Lust, greed, anger, envy pride etc. We must meditate constantly to observe and remember ourselves, to be constantly awake. We must be conscious of what we are doing and see if it's pure or utilized by an ego.

"The ego is a multiplicity of contradictory psychological elements that we have inside, and are in their sum, the "ego". Each one is also called "an ego" or an "I." Every ego is a psychological defect ..."

Mark 5:6-9
6 When he saw Jesus from a distance, he ran and fell on his knees in front of him. 7 He shouted at the top of his voice, “What do you want with me, Jesus, Son of the Most High God? In God’s name don’t torture me!” 8 For Jesus had said to him, “Come out of this man, you impure spirit!”

9 Then Jesus asked him, “What is your name?”

“My name is Legion,” he replied, “for we are many.”

Every Psychological defects must be actualized and burn into cosmic dust. We must constantly remember ourselves, we must remember and pray for God to help us. Every impurities that we have must be purified by the power of God. Be awake! May all beings be Happy!

Psychology is not biblical and was invented by one man and popularized by many.
