if we are using the Course as a benchmark, and its logic, the ego is always insane. You can rise above ego by seeing it clearly and not acting out of fear and ego. Level clarity is knowing the difference. Ego is not you, it may speak first but it is not you 

¹⁰Concerns about the body demonstrate how frail and vulnerable is your life; how easily destroyed is what you love. ¹¹Depression speaks of death, and vanity of real concern with anything at all. (ACIM, T-27.I.6:10-11)

 3. When you are sad, know this need not be. ²Depression comes from a sense of being deprived of something you want and do not have. ³Remember that you are deprived of nothing except by your own decisions, and then decide otherwise. (ACIM, T-4.IV.3:1-3) 

 ⁶When you equate yourself with a body you will always experience depression. ⁷When a child of God thinks of himself in this way he is belittling himself, and seeing his brothers as similarly belittled. ⁸Since he can find himself only in them, he has cut himself off from salvation. (ACIM, T-8.VII.1:6-8) 

³Depression means that you have forsworn God. ⁴Many are afraid of blasphemy, but they do not understand what it means. ⁵They do not realize that to deny God is to deny their own Identity, and in this sense the wages of sin is death. ⁶The sense is very literal; denial of life perceives its opposite, as all forms of denial replace what is with what is not. ⁷No one can really do this, but that you can think you can and believe you have is beyond dispute. (ACIM, T-10.V.1:3-7) 

Luke 17:20–21

20 Once Jesus, was asked by the Pharisees when the kingdom of God was coming, and he answered, “The kingdom of God is not coming with things that can be observed; 21 nor will they say, ‘Look, here it is!’ or ‘There it is!’ For, in fact, the kingdom of God is among you.” 

1 Corinthians 12:13

For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit. 

1 John 4:16

Matthew 5:14-16 14 “You are the light of the world, let your light shine before others.

Psalms 82:6 I have said, Ye are gods; and all of you are children of the most High.

1 Corinthians 3:16 Do you not know that you are God's temple and that God's Spirit dwells in you?

John 17:20-23 “I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us.

²Depression is an inevitable consequence of separation. ³So are anxiety, worry, a deep sense of helplessness, misery, suffering and intense fear of loss. (ACIM, W-41.1:2-3) 

8. There is nothing so frustrating to a learner as a curriculum he cannot learn. ²His sense of adequacy suffers, and he must become depressed. ³Being faced with an impossible learning situation is the most depressing thing in the world. ⁴In fact, it is ultimately why the world itself is depressing. ⁵The Holy Spirit’s curriculum is never depressing, because it is a curriculum of joy. ⁶Whenever the reaction to learning is depression, it is because the true goal of the curriculum has been lost sight of. (ACIM, T-8.VII.8:1-6) 

when you are tempted to judge read this vip.  judging causes depression. 5. When you feel tired, it is because you have judged yourself as capable of being tired. ²When you laugh at someone, it is because you have judged him as unworthy. ³When you laugh at yourself you must laugh at others, if only because you cannot tolerate the idea of being more unworthy than they are. ⁴All this makes you feel tired because it is essentially disheartening. ⁵You are not really capable of being tired, but you are very capable of wearying yourself. ⁶The strain of constant judgment is virtually intolerable. ⁷It is curious that an ability so debilitating would be so deeply cherished. ⁸Yet if you wish to be the author of reality, you will insist on holding on to judgment. ⁹You will also regard judgment with fear, believing that it will someday be used against you. ¹⁰This belief can exist only to the extent that you believe in the efficacy of judgment as a weapon of defense for your own authority. (ACIM, T-3.VI.5:1-10)
