This is not to encourage myopic vision and discourage an outward orientation to the world. It is not about focusing on the self and not caring about the needs of others. It's simply about paying attention with care to what needs to be done at the moment, not trailing off into stories on the imaginary horizon and dividing our energies. The ability to give up the worry and stories finds its origins in fearlessness and bravery. This is the tradition of the spiritual warrior that Chogyam Trungpa Rinpoche talked about.
My use of the image of a cage reminds me of a Zen story about a golden bird locked in a cage. The bird struggles to get out but the door is closed. Turns out in, amidst all the struggling and flapping about, the bird neglects to look down and see that the cage has no bottom.
What cages do you live in? What ones have you set yourself free from, dear lovely birds of the great virtual sky?
