So, in one sense, one might claim that Hinduism is older than “CHRISTianity” because it dates back before Christ.
I agree.
I had mentioned earlier that there are similarities between some passages in the bible and those in the Bhagavad Gita preceding it:
Bhagavad Gita: I am exceedingly dear to the wise man; he also is dear to me. (Ch. VII. 17)
New Testament, Bible: He that loveth me shall be loved by my father and I will love him. (John XIV. 21)
Bhagavad Gita: I am the way, supporter, lord, witness, abode, refuge, friend. (Ch. IX. 18)
New Testament, Bible: I am the way the truth and the life. (John XIV. 6.) I am the first and the last. (Rev. 1. 17)
Bhagavad Gita: I never depart from him, he never departs from me. (Ch. VI. 30)
New Testament, Bible: He dwelleth in me and I in Him. (John VI. 57)
Bhagavad Gita: They who worship me with true devotion are in me and I in them. (Ch. VI. 29)
New Testament, Bible: I in them, thou in me, that they may be made perfect in one. (John XVII. 23)
Bhagavad Gita: Be assured that he who worships me, perishes not. (Ch. IX. 31)
New Testament, Bible: He that believeth in me shall never perish, but shall have eternal life. (John III. 5)
Bhagavad Gita: I am the beginning and the middle and the end of things. (Ch. X. 20)
New Testament, Bible: I am Alpha, Omega, the beginning and the ending. (Rev. I. 8)
Bhagavad Gita: I will deliver thee from all sin; do not grieve. (Ch. XVIII. 66)
New Testament, Bible: Son, be of good cheer, thy sins be forgiven. (Matt. IX. 2)
Bhagavad Gita: What sacrifice, almsgiving, or austerity is done without faith is evil. (Ch. XVII. 28)
New Testament, Bible: Whatsoever is not of faith is sin. (Rom. XIV. 23)
the main point is whether practices of eastern mysticism/kundalini should mix with Christian practice
Whether it should or shouldn't, it apparently did. If Christianity can be influenced by things they way it is today, there's little doubt in my mind that it was influenced by things way-back-when.
And again -- a point I've made previously that seems to get glossed over, probably from an underlying fear in some hearing it that God really
does speak to/through those other "unworthy" religions as much as He speaks to/through Christianity -- it may not even be external influences from other religions that create the similarities, but rather those religions simply getting the same Divine messages from Him on those similar points. Like I said, a room of pianos all tuned to the same fork are going to be in tune with each other. Granted, this suggests that maybe Christianity isn't God's one and only favorite, but then I don't think His mission was to form an exclusive social club to begin with, so this really shouldn't even be an issue.
