Being open to anything that comes in our way allows more things to flow in our lives.  Our expectations of how things should be keeps up stuck in our old ways of thinking and doing.  We must learn to be flexible at any moment.  The Universe or God can allow more in to flow our way when we just accept things to flow without judgements and preconceived notions of what needs to be or what should be.  I have learned to accept and let go.  Surrending to all that is can create fear and anxiety, but at the same time if we are ready and willing with courage and commitment then anything is possible to move us forward and release us from our own chains of suffering.
