Based upon your profile, I can convey this to you using lingo you may be most comfortable or familiar with.

Sarcophagi are the origin of the practice of "baptism". They were used as sensory deprivation chambers to catalyze what you might have heard referred to as "the fiery baptism of the Holy Spirit".

Other traditions would have other names for this.

Hermetic Alchemists would call this "salvation".

Hindus and Nagas would call this "Kundalini awakening".

Kabbalah students (Egyptian and Hebrew alike) might call refer to it using terms like "da'ath" which clearly connects to "born again", amongst other similar concepts (Phoenix rising from it's own ashes, metanoia, the dark night of the soul, djinn "possession", etc.)

It is supported by science in half a dozen capacities. It boils down to a certain "brain oscillation" that triggers the process.

As another connection for you, the word Christ utilizes the Greek letters Chi and Rho...Chi Rho...Cairo. That is not a coincidence.

Christianity contains within it what some might refer to as "the perennial philosophy". If viewed from a very specific perspective, every religious tradition is essentially pointing at the same cosmological truths. They each leverage different lingo and each tradition tends to be subject to varying degrees of distortion over time but based on what I've seen, they're all consistent in specific ways.

Dogmatists tend to dislike me but I prefer to take the whole "love your neighbor" thing seriously and explore the ways that all of my human neighbors express reverence for the Creator even if their terms and customs are different from what I was raised with.
