New age is hard to pin down to one set of doctrines, so noone can say it is satanic or not. Also waht christians call new age is raraly what people who calls them selfes new age means. Lot of confusion.
There are streams that is in line with the words of jesus, some of it literally buildt upon the words of jesus, honors god as the only creator, and there are others that probably communicates with fallen spirits.
the koeran dude said it is satanic because it tries to bypass the mind. This is not true at all. Most spiritual teaching buildt upon a eastern philosopic system sees the mind as a gateway for the spirit - exactly like jesus would say "the eye of the mind is the lamp of the body, you either keep it single, and it releases light and your whole body will be filled with light, or you keep it double minded and it blocks the light, and oh how gret the darkness then will be" kinda thing. It sounds very "new agey" but it is actually god in flesh teaching here. The opint in most eastern spirituality when it comes to the mind is to keep it pure filled with awareness (watching) rather than cosntanctly inner dialog/monologue....whjat we call obsessive thinking.
This "watching wa also taught very clearly by jesus many places, as he even told them that real un felshy powerful spiritual prayer is called "watch and pray" (for the spirit is willing)...and another place, this i tell you all "watch".
And rememebr judaism was not from the west! Jesus was not a westerner, and abraham literally came from these parts of the east....the "new age" parts....thats our father of faith, so we need to be craeful of what we call satanic....korean dude from asia......
