ippy...It doesn't matter if you don't believe. :) That is just your path of development. You will also get there like everyone else. Maybe in your next birth you will be a Yogi living in the Himalayas...you never know! ;)

Making someone understand is very difficult. Taking the simple instance of the moon landing deniers. How can you possibly convince them that people have actually landed on the moon? Anything you argue or show them could be mocked and dismissed. That is the way their mind is programmed and that will not change easily.

Similarly, if someone does not believe that there is anything beyond the mundane realities of the body, earth and so on, there is nothing anyone can do to convince them that there is something. All philosophy and detailed spiritual teachings are for those who accept them in the first place.
