The most valuable experiences of our lives, those that have the deepest impact on our paths to becoming and expressing who we are, must sometimes cycle in and out of our lives for a while--sometimes years--before the time is right for us to reach out and claim them as our own.  They come into our awareness when we are in a space of curiosity or vulnerability, a space that lends a certain stickiness to our minds and hearts.  It's just sticky enough to capture a lasting impression of the potential that this experience could hold for us.  Some day.  Not today, but some time in the liminal future.  When we are ready, or curious enough, to step into it.
