The often-painful experience of any personal limitation is our awareness of a difference between some higher ideal we feel drawn to actualize... and our (present) inability to fulfill that possibility; but, to be clear, this pain is not -- though it often seems to be -- proof that we’ve gone as far as we can go! In truth, the revelation of any limitation is a Divine invitation to walk into, and through it. To what end? To make the discovery there is no end to self-realization... to transcending who, and what we have been up until that moment.
What we are able to do today -- or not, should that be the case -- does not determine what's possible for us “tomorrow”. That is to say... unless we unconsciously agree to believe in the authority of “yesterday”.
