It's to start a new life in Christ. We were made in His image but we fell away and sinned. Baptism allows us to remove the old man and live our life as a new man in the likeness of Him again. This is the new birth. No longer living by flesh which will die but by spirit which shall live forever in heaven.
Many people interpret it in this way, accepting Christ into one's life, accepting His commands, and that the water resembles the womb and thus we are born again.
I always add my esoteric approach, which only people who are essentially outcasts of society, due to their supernatural abilities.
Everyone has an astral body, but about 5% of people ever astral travel, and probably less than 1% astral travel nightly.
Our spirit body, or astral body, is capable of going through time and walking through walls.
Because of evil, most people never experience it until they have a NDE, which is a near death experience.
People who has NDE's report they raise out of their body and realize they are dead, or at least they think so.
Usually they try and get back into their body and wake up.
If everything said is taken 100% factual, then you would know people can leave their bodies and do at death.
There is another interpretation to be reborn again is to not only be born into the physical body and world, but also the spiritual body and world. Most people have trouble with lucid dreaming, astral travel is the next level. Dreams are within, astral travel is without.
I try and I try to get people to accept this reality, but people are not willing to put in the effort to experience it, and never believe.
People are confounded by the lack of knowhow and group together against me as if I am crazy.
John even said "Immediately I was in the spirit," people can go into spirit whenever they want if they are able.
This is what it means to me anyways.
Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Baptism is signifying you are restarting your life, hence being freed of the sins prior to the discovery of Jesus and washing them away.
The body is purely flesh, yet the operator of the body is spirit, yet people never seem to experience the spirit without the body.
Why then do THOUSANDS of people speak of spirit travel, astral projection... C'mon people
Hinduism puts it this way. ..
Level of consciousness:
Body you have to rise above body
Desire you have to rise above desire
Astral Body and you can astral travel

To me, because it is a second body, that is spirit, and not flesh, this is born again.
born of flesh = living in the world, if one only sees material things then one identifies only with the physical body and world
born of spirit = spiritual initiation
