“If you fall into poverty, live that way without grumbling - then your poverty will not burden you. Likewise, if you are rich, live with your riches. All this is the functioning of Buddha-nature. In short, Buddha-nature has the quality of infinite adaptability.”

“You must realize that no matter how intently you count your breaths you will still perceive what is in your line of vision, since your eyes are open, and you will hear the normal sounds about you, as your ears are not plugged. And since your brain likewise is not asleep, various thought forms will dart about your mind. Now, they will not hamper or diminish the effectiveness of zazen unless, evaluating them as "good", you cling to them or, deciding they are "bad", you try to check or eliminate them.”
