How do I know for sure if I am feeling Oneness?

Oneness is actually an experience that is priceless and beyond words.  It is like a sense of pure flow within.  A knowing that the connection to your core within is solid and smooth flowing.  A knowing that all is well in the present moment.  A knowing that you have reached a depth level that makes you whole and undivided.  It is an experience that is well worth the effort of self-discovery.
