The dizziness in the face of les espaces infinis-only overcome if we dare to gaze into them without any protection. And accept them as the reality before which we must justify our existence. For this is the truth we must reach to live, that everything is and we just in it.
There are no mistakes in Zentangle, so there is no need for an eraser. If you do not like the look of a stroke you have made, it then becomes only an opportunity to create a new tangle, or transform it using an old trusty pattern. A Zentangle tile is meant to be a surprise that unfolds before the creator's eyes, one stroke at a time.
Your life is your practice. Your spiritual practice does not occur someplace other than in your life right now, and your life is nowhere other than where you are. You are looking for answers, insight, and wisdom that you already possess. Live the life in front of you, be the life you are, and see what you find out for yourself.
We grow up to believe that we are supposed to somehow "become" who we are meant to be through the trial-by-fire that is life here on planet Earth.
Reality is...there's no "becoming".
It's actually all an "un-becoming", only to reunite with who you were born to be in the first place before society told you otherwise.
