well, from that point of view yes, we are everything, but as i can say, very few people who can meditate can go into the deepest part of their minds... as into getting to the astral plains (as i was told were called) as every spiritual being from gods to demons have been in those plains, from what i learned, ''heaven'' and ''hell'' do exist, but in a more spiritual form than anything else, though don't think the world is connected on a flat surface, think of it as a drop of water, connected like H2O, but its connected to everything that your mind may access... some can even go to their own inside world, as such there is the ''creation plain'' as to what ive heard of it, and ive been there... nothing special but making a new plain.
