I have been through most of the wookbook from A Course in Miracles (ACIM), and find it to be the closest formal statement I have seen to what our spiritual nature is like. It teaches one to assume our true nature which is sacred and holy, and allows us to envelope the world, and our neighbor, and our families, and our enemies, with our holiness (love).
ACIM is not a religion, but it could be easily placed into any of the major religions as a practice. In fact, knowing most of the major religions very well, I believe all of them could benefit by ACIM teachings.
ACIM teaches gratitude, generosity and forgiveness. It teaches one to find our true holy nature, and to be able to act in the world with integrity and blessing.
Here are 2 quotes from ACIM:
I have indeed misunderstood the world, because I laid my sins on it and saw them looking back at me. How deceived was I to think that what I feared was in the world, instead of in my mind. (p. 418)
Let every voice but God’s be still in me. Today we let no ego thoughts direct our words or actions. When such thoughts occur, we quietly step back and look at them, and then we let them go. (p. 411)
Be blessed today.
