What scares me is the belief in Nirvana and other Buddhist teachings. You don't really exist at all ever. You are like a clear bottle of sea water in the ocean floating on the top. Just being tossed by the waves until you "realize" that bottle doesn't really exist. You can only be free, cured, and find the still waters that run deep by realizing you don't even exist at all! I got comfortable with it after I first learned it 14 years ago but at the time it was a terrifying thought as I was completely open to it and came to believe it for a time.
Later I was told and read that in fact many Buddhists and other Easterns (Jains, Hindus, etc.) do not see it this way. A Central Asian Buddhist told me that they believe something that bears similarities to Theosis. The Enlightened Ones are Buddhas and Bodhisattvas. They still exist but enlightenment has made them gods who have no need or attachment to anything material. She, the Central Asian Buddhist, can't remember what ethnicity, told me that it is a false western Dualism that misinterprates what they teach and attach false, negative and evil concepts and ideas where they don't exist, such as that Nirvana is complete nothingness and non-existence or that material is evil rather than attachment, that is like addiction, to the material world.
Also with regards to the comment on Christ speaking in Dualisms I have to emphatically deny this!
Christianity has no dualism. Evil has no real existence as there is no such thing as absolute evil. God created everything very Good. It is the free will rejecting God that is evil but God is Good and All Powerful. Evil has no permanence, no Life, no Truth, no reality or essence.
Only God is totally Real.
In the Bible there are paradoxes and simple oppositions but nothing that equates to dualism as it is used and understood (Good vs. Evil)
My understanding of Theosis is related to the Sacrament of Marriage. The two shall become as One. Now we all know that there is a sexual meaning to this but it is much more that that of course.
Christ is the Bridegroom and we are the brides.
God made us out of Nothingness.
To be united with God is to become god. To have Love, Life and Truth in Full!
I suppose I am too used to this to be scared by it.
I have to say what gnaws at me is the fear of death as the end. I lived for several years not believing in anything much and convinced myself that there can be no afterlife.
To have nothing after all this is a dreadful thought.
Atheism scares me . . .
