When did you know, I mean REALLY KNOW you were a part of it all?  My realization was when I was getting my Master/Teacher Reiki Attunement in the late 1990's.  As I lay there with Rebecca Kurtz doing the attunement, I silently asked that I didn't have to do the work alone.  At that moment it seemed as though there was a loudspeaker at full volume in my head.  The words were simple and the voice was male.  The words were "you are not one you are a part of it all".
A part of it all.  Hmmm, I finally felt that it didn't matter if others were physically near me.  I wasn't alone doing anything. I could just acknowledge that there were others helping me in whatever I did. I just had to ask the question and listen for the answer. The listening doesn't have to be with the ears or even the voice in the head...but also in sight or feeling. I have asked questions to "it all" and received answers in the form of license plates, songs on the radio and paragraphs or titles in a book that happen to open at just the right place.
Being a part of "it all" is becoming more interesting as I ask more questions and get more answers faster and faster. There seems to be things happening at a faster pace. Is it because I know? Really Know?
