I'll begin by stating some information that may put many people off to the story. For many years, I have had the experience of hearing thoughts which appear to come from an external source.
I have no idea what it could be. I've approached it from a standpoint of psychology, spirituality and everything in-between, in the end it is just a part of my experience of life, and has largely been positive.
Many times offering insight and advice far beyond my own personal wisdom and understanding. The greatest aspiration in my life is seeking an understanding of exactly what life is, who and what we are, an unending curiosity for exploring what this absurdly strange experience is. This is usually the content of exchange with this voice.
Now for the experience, one night while sitting outside staring at the stars, pondering many of these questions and realizing the apparent futility of seeking an understanding of life by pure brute force thought, I was extremely overemotional, deeply sad and begging this voice to show me the 'truth', a truly poor question in hindsight. What happened next is probably the single most intense experience I've ever experienced.
Pure unconditional love, radiating with an intensity that is beyond anything words can describe. Tears instantly fell from my eyes like a waterfall, and during this experience there was also a dim understanding of what I was experiencing, and the only way I can describe it is that this love was the heart beat of the universe.
I was staring at the universe, and found that what was staring back, was myself.
