Hi this is a really interesting question, my Mother in law was convinced she had a past life, she went to a ashram in India, it seams that everyone there has a similar past life and that they all knew each other then, were they all under the influence of suggestion, after long meditation sessions and strict diet, which sounded like a bunch of leave and water for 4-5days.

Here personality was changed by the experience, she kept in close contact with all the people, who supposedly had shared past lives together.

From what I understand you are told to closed your eyes, the person then talks about opening your third eye, you walk towards a light, there is a passageway, sone people are said to have one or two doors, we’re others there are many doors.

you are told to open the door and look insid, you are told to say what you see and what you hear,

This is an interesting question. The law of identity and individuation are important concepts in understanding both the afterlife and faith. Occam's Razor postulates that the simple answer or conclusion is the correct one. However, in its pursuit of simplicity it can also reject concepts that do not fit its mandate. There are times when the correct conclusion may involve greater structural diversity and complexity. When discussing the after life there is little "proof" to lean on. Their are personal experiences of death and return to life that testify of seeing or being in another place, apart from our physical earth, that suggests a place where Divinity resides. But the belief in Divinity is simply that, a belief, that cannot be proven by hard science. Faith becomes the proof as experiences are interpreted to be a result of divine intervention.

Faith is not wrong. It is part of human experience. It is exercised daily in many forms. I have faith that what I am typing on my computer will be transmitted through the air, or electrical connections or some other means unknown and not understood by me, so that the writer of the question can read my response. When I sit down in my chair I have faith that it will support me.

Faith in the afterlife has profound implications for the one who believes. It can change how they respond in their current life, the choices that they make, and the identity of self that they have. It suggests an interaction between the individual and that which is beyond human identity, or the Divine.

Occam's Razor has long been used by creationists to explain why creation by a Divine Being is a simpler explanation for all that exists, than evolution by chance, which presumes a multiplicity of extreme changes over time, which result in the world as we know it, in all of its complexity. Evolution goes against Occam's Razor by postulating that the world has gone from simplicity to complexity. From an undifferentiated soup of elements and compounds to the complexity of a single cell.

I myself have faith in the Divine, and of an afterlife. I work with people who are grieving as a therapist and researcher, and find that those who have this kind of faith, while they still grieve deeply, grieve differently than those who believe that there is nothing after this life. In that sense, the belief contributes to a greater sense of peace and purpose in the individual's life.

Again, an interesting question.
