Spirituality means something different to everyone. It does not necessarily mean religious, although its does not necessarily mean if you follow a particular faith that you are on the right track. The thoughts about spirit revolve around the fact that our bodies are different than the energy that occupies our bodies (spirit).
“Energy cannot be created or destroyed, it can only be changed from one form to another” - Albert Einstein
So what was our energy before we took this form? What will it be afterward? What energy decided for us to exist? Is that energy God, The Universe, The Force?
When you figure out what spirituality means to you, and open your mind to how much truth and expansiveness you are willing to receive, your perspective will change.
