The interesting thing about all blocks to awareness, is that there is always love behind them. The block is there to hide the love. The block also makes it seem like the love is not there. But if you were to remove the block, you would return to the awareness of love's presence, which has been there all along. This is why behind every grievance there is a miracle of love.
"The miracle behind this grievance will resolve it for me."
"The answer to this problem is the miracle which it conceals."
We began in love and we love everyone and everything. But then along comes ego stuff, grievances, hates, judgements, blame, anger, fear, guilt, sinfulness, darkness, to blot out the love and cover it up. But we truly do simply "cover it over" with a layer of untruth, to disguise it and make it seem like it's not there.
This means that no matter who you seem to be angry towards, you actually do love them behind that anger. Behind all physical objects there is also love. Behind the body there is love. Behind all attacks and judgements you love the thing you are attacking and judging. Underneath your hatred there is love. And beyond every layer of self condemnation there is love. It's already there, because it's your love of God which nothing can remove.
The course says that grievances and miracles are opposite. That a grievance hides a miracle. And if you apply forgiveness to the grievance to undo it, you will become aware of the miracle instead. ie if you remove the block to love, the love is revealed. It's kind of like removing the clouds so that the sun can shine. The sun is always there behind the clouds.
It's not as if, when you're in a grievance, there is no love anywhere. It does seem that way because a grievance is a denial of love, it's an attack and a belief in sin. Every grievance attacks love and attacks God and the sonship. But it does this only in an attempt to make it go away, which ultimately is a form of denial. You can't make love go away because love is permanent. All you can do in truth is hide it from your awareness and pretend it's not there. Like burying your head in the sand.
If you can remember that behind every grievance there is a miracle of love, then you know that the purpose of every grievance is to hide the love. And that means every grievance implies there is love there, a love which you're trying to use the grievance to hide. The grievance is serving a purpose of avoiding the truth. Admitting to the truth and waking up to reality exposes you to love again.
To do that you need to recognize the attack is there to serve a purpose. You aren't just attacking for no reason, or even just because you want to get rid of your sin and guilt. You're doing it to achieve a goal of keeping God away. Every attack upon yourself and every projected attack upon others, is only there to serve the goal of separation from God. You use it for that reason alone. You want to keep the separation going so that you will not be exposed to love.
"Projection will ALWAYS hurt you. It reinforces your belief in your own split mind, and its ONLY purpose is to KEEP THE SEPARATION GOING."
The removal of the blocks to love's presence, is merely the removal of all attempts to attack. Attack is sin, and also insanity. You can only attack yourself, so each time you are attacking you are trying to hurt yourself. Doing that hides your awareness from love, and is really the purpose of the attack. The aim of all attack is to resist the truth, to shut God out, to hide from reality, and to assert that you are not immortal. But without attack, only the truth of love remains.
