If you are more religious or spiritual, travel through whatever you conceive the ALL to be. Don't be afraid to wonder how God or spirituality exists, and so make the same journey to the very beginning of all being. Don't be afraid of nothing either. These are simple ideas and beautifully simple questions. We say the word nothing everyday.
Nothing is nothing to be afraid of.
Imagine that we carefully approach the beginning of time and stand there at the very edge where existence begins, as if we've walked out to the edge of a cliff, and now try to imagine beyond the precipice upon which we stand. Imagine the abyss of nothingness that would have been prior to existence, and try to understand its nature. Reach out with your hand to touch it. Try to think of a word to describe what is there. Of course, if you are able to describe something, or imagine something, or even feel something, your giving nothing qualities it doesn't have.
