I prefer the western European account that Jesus may have visited Britain with His uncle Joseph of Arimathea. There's an ancient legend in Britain that called him Joseph the Tin Man, because Joseph was a trader in ores, and Britain was reknown in that time for its ores.
That makes more sense than the pagan accounts that say our Lord Jesus traveled to India and Egypt to be initiated into the so-called ancient 'mystery schools'.
The mystical fraternities would love nothing more than to fool its students into believing that Jesus was one of 'them', having been initiated into their 'mysteries'. In one shot that delegate the Ministry of Christ Jesus as The Only Begotten Son of God down to mystic holy man sage status, and as a FOLLOWER of 'their' pagan mystery schools of pagan initiation.
So yeah, just maybe Jesus did travel to India, or Tibet, or Greece, or Egypt, during The Bible's missing 18 years of His life, and participated in blowing the long horns of Tibet, meditating with the Tibetan monks to make mandalas, spin their prayer wheels in repetitous prayer, heed their doctrines of reincarnation, charm some snakes in India, fly some carpets in Arabia, and maybe even pratice levitation exercises and making objects appear and disappear!!! Afterall, aren't Buddha, Zoroaster, Muhammed, Krishna, etc., all equals to Jesus Christ?
No, they are not, and that's why Satan's host have promoted such ideas among the pagan mystery schools of occult initiation. It's so as to fool their students into thinking they can become their very own 'god', and by theirselves save their own souls.
