Wow, that is very interesting, (the third desire) I think I understand. I Believe I have experienced it, but have never linked it to a desire, but now that you mention that question; "Now that I feel complete, how do I share this Ecstasy with others?" That "desire" is something powerful I experience and never really understood why it was so important for me to share.
I'm not sure if I've totally experienced the total completeness, but during certain meditations or times of grasping a new level of knowledge that I know to be true deep down, its like everything else is irrelevant. Very hard to explain.
Thanks for putting your perspective on the subject of desire. It is something I am going to pay more attention to moving forward.
