GAUTAM -Buddha(BUDDHADEV) and The capability of having several lives for an ordinary man or hallucination? A friend of mine said GAUTAM-Buddha(BUDDHADEV) passed through several lives(Births and Rebirths)and finally he attained NIRVANA.In present day context do the experience s feel like walking on an Astro-turf or living in mothers womb.This is my personal experience which should not be considered BLASPHEMY.I divulged my experience to my friend.So he advised me to search books.After death is such an experience possible?
the path to Nirvana is very simple logic. Here's what I learned from my teacher:

You should divide everything you do (including every word and even every thought) in two groups: whether you're doing it to feed your ego or whether it's actually useful. You have to be very precise. Very precise, with every single word and every single thought you should know why you're doing this. If it's for defending the ego or indulging in pleasure, you should not do it like that, should not think like that or say that. If you're doing it because you think it's actually useful, then you should do it.


  Bhikkhus, before my enlightenment, while I was still only an unenlightened Bodhisatta, it occurred to me: ‘Suppose that I divide my thoughts into two classes. Then I set on one side thoughts of sensual desire, thoughts of ill will, and thoughts of cruelty, and I set on the other side thoughts of renunciation, thoughts of non-ill will, and thoughts of non-cruelty. MN 19


Then, when you live like this for several years, your mind will be pure and you will be able to see the path to Nirvana by yourself.


  To avoid all evil, to cultivate good, and to cleanse one's mind — this is the teaching of the Buddhas. The Dhammapada 14.183


My teacher said, this world is a magical place where everything is possible, as long as you're free in your mind - and now I know he was right.

So, divide your thoughts like that, and learn to be very very precise with that - and you will see for yourself. This is better than me telling you "Yes, All of that is real". Hope this helps.
