Who are you?  This is the most important question you can ask, followed by “Why am I here?”  The answer to the first question provides the answer to the second.  You are spirit experiencing itself through a temporary role.  Why would you choose to do so?  For the experience and the growth of the whole … to bring into experience a world of possibilities aligned … to let your light shine.  When it does not shine, you do not feel so good, do you?  That is mis-alignment.  What does feel good?  Loving, caring, connecting.  This is alignment, harmony, and that is why you are here.   Model these attributes and see what happens.  You will then know precisely who you are, Love.
