A spirit world or all in our mind?

I believe the mind is the most powerful thing that human beings have . I also believe that anything is possible if you make yourself believe it . It may not be true in other people's minds but that's what separates us . All truths were originated from ideas once not known yet or discovered . If your mind decides something is real , you have opened a new channel for growth in areas leading from that point . Be careful what you decide is real . I suppose the spirit world could all be in our minds but certainly it;s is being envisioned through our minds . Enjoy this world while you can, time is short and you may never know the truth .
