Imagine for a moment a flower or tree, letting go a seed, which is then picked up and blown away by the wind, far from it's original home. The seed is carried long distances, eventually touching down elsewhere and taking root. The seed does not spend it's days trying to get back to it's original home, wishing it could go "back" or be somewhere else. The seed understands that in this Universe everything has it's rhyme and reason, and it has been taken where it is next intended to be. So it follows it's very nature, takes root, and builds itself into the reality it now finds itself in.
This is the eventual path of all awakened beings on Earth; to accept that nature has placed us where the winds have blown us, for a reason. We are to take root, to become native as it were, and to flourish and abundantly grow.
It is also the nature of the Universe that we all have free will to choose our experiences, and perceive through our own sense of understanding and awareness. If you are a seed who has been blown to a place which does not support or nurture you, rather than dreaming listlessly of the life you wish you had, you can consciously begin to build your life around you in the way which you desire. This takes dedication and commitment, honesty and perseverance, and yet is ultimately more gratifying than a life spent wondering "what if."
Life is not a puzzle to be solved but a game that wants to be played.
