Is there any difference between the sensation/emotions of being 'saved' whether you are a fulfilled follower of Christianity or any other religion?

It depends on who you ask.

Most Christians would claim that the epiphany that lead to their experiencing God was profound and unlike any other.

Psychologists and sociologists have long noted that the avalanche of emotions when someone arrives at a new worldview is indeed common and not restricted to Christianity. They call this the conversion experience and troubled believers have even experienced it when they gave up their beliefs.

I would say no. I am Christian, and I have actually discussed this with a friend who is Muslim, and we found that the way our beliefs make us feel is remarkably similar. I see no reason for what I feel to be anymore profound than something experienced by someone of a different faith. Their faith is just as true and real for them as mine is for me.

What about Christians who become Muslims - is this more a technical move, like Bishop John Broadhurst converting to Catholicism? Kinda like shifting from Tea Party to Republican maybe, except you go to a different Heaven? I still can’t get my head round how an earthly conversion is recognised in the Heavenly universe, such that there is a handover process ‘up there somewhere’ - presumably St Peter’s and Lucifer’s databases are updated, in effect - following an obvious change of heart by a soul on Earth. I did wonder if converting to Buddhism counted as ‘saved’ in that you are then on the reincarnation cycle and many count that as a blessed place to be.

Interesting isn’t it, I’ve had many epiphanies - some quite unnervingly profound - in the last 5y. Whilst a reflex omg, a pile of spine-tingles and the need to sit and dictate/reflect occurred - which some might consider meditation, no ‘conversion’ was involved. However I do now see planetary society in ways I had not previously noticed. Epiphany to me seems to be a Eureka moment, when a critical mass of data connections occur simultaneously in the brain. It is very well documented in biblical texts and Christian marketing, because religion (specifically Christianity) was traditionally the only place it happened. All the equally powerful moments - assisted by the rituals associated with their own disciplines - that scientists, leaders, managers and other visionaries have had are just written down as ‘great discoveries’ or ‘gifts of God’. The latter tag only applies when the discovery is perceived to benefit Christianity however, so Darwin isn’t a saint because he was not recorded as having had a Religious epiphany. Yet by the standards applied in the 1st millenium CE, he would have been far more visionary than someone like St Boniface, perhaps, except his findings did not seem to align with those of earlier observers. But I digress. Ritual is a powerful tool - hence its ability to achieve higher consciousness states through rituals of meditation and yoga, and even tantric sex. Another aspect of this is the use of pain by Hindi and Buddhist adepts, certain Catholic adepts (if we take Dan Brown at his word) and - I struggle for an adjective here - adepts of SM sex. The unlikely commonality that appears in this pattern seems to suggest that the state is hard to achieve solo, and the neural chemistry for higher awareness and exalted ecstatic states only fires after a progressive education and teaching process involving extensive ritual. Hence, going back to the beginning, I could generalise and say that epiphanies are critically ecstatic moments of Learning - and I note that prior to modern times religious institutions/individuals were the only Recorded imparters of deep knowledge, though Solomon is an interesting case. Can you suggest any references to look over for the psychology?
