We are animals with animal needs, urges. Now to preserve and cultivate life, make it evolve and become eternal (God(s), we need spiritual guidance. Spirituality cannot be removed from who we are. We all need a strong spiritual base to make good use of our minds and bodies. We are molecules in a test tube and someone is watching above, just like we re watching our kids from above. Nothing is lost, nothing is created, everything is transformed. We know what our bodies become once we die, what about our minds? Why would they simply disapear? One thing is sure heaven is not on earth. It means it has to be somewhere else? How comes we will probably never be able to leave the planet? How comes scientists see the probability there might be other "mankinds" in the universe ? How comes we have the hability as humans to understand the perfection of everything that surrounds us, while other animal species cant?
Now there's spirituality, and spirituality. Many people are "mystic", and dont want to believe or be labeled as belivers. But we all believe in something bigger. We can all sense it. An order in things, "karma" etc. Just like in the physical conditioning world some paths are leading nowhere and only the natural, healthy way is the right way, in the spiritual world there are many choices to choose from, but only one is the real deal.
Our minds aren't a thing but a process, the answer as to what happens to the "mind" is contained within the definitions. For example, birds migrate, however you don't ask what happens to migration when the birds die? or how about a picture in a film of the ocean, if you open the camera water doesn't spill out, the mind analogous to migration and the ocean, the brain the thing. This idea you have is called duality and is debunked firmly, we are molecules in a petri dish but it appears no one is watching.
The perfection of everything around us? what is perfect? I could do a far better job making a perfect world. Think about our eating and breathing, the same hole? this means people will die trying to eat, dolphins avoid this issue. How about the perfect eye? half of the people living nowadays have eye issues. What about my dick? It is both a play toy and disposal unit opening up all sorts of shitty possibilities, hehe.
Where you see something mystical, I see pseudoscientific ramblings, where you see perfection, I see utter chaos.
