Anxiety and Grace

"In God's bounty there is no retrenchment or reduction...
(God says)"Give the hidden pearl to everyone who desires it.
Scatter the daily bread recklessly.
Release those in debt from their responsibility: like rain make the carpet of the earth green."
What is this feverish trembling for fear of hunger? In possession of trust of God one can live full-fed.
There is in the world a green island, where a sweet-mouthed cow lives alone.
She feeds on the whole field until nightfall, so that she grows fat and big as a mountain crag.
During the night she becomes thin as a hair from anxiety, because she thinks, "What shall I eat tomorrow?"
At the rise of dawn the field becomes green: the green blades and the grain have grown up as tall as a man's middle.
The cow eats ravenously from her hunger; til night she feeds on that vegetation and devours it entirely.
Again she becomes fat and stout and bulky: her body is filled with fat and strength.
Then, again at night, she is stricken by panic, and falls into a fever of anxiety, so that from the fear of vainly seeking for fodder she becomes lean.
Thinking, "What shall I eat tomorrow at noon time?" This is what the cow does for many years.
She never thinks, " All these years...my nourishment has never failed, even for a day: what then is this fear and anguish and heart burning of mine?"
You have eaten for years, and the food has never failed: leave the future and look at the past....do not be miserable."

Rumi (Vol.5, 2791-2869)

Commentary: I must give up this diet of anxiety! All this grace, for so many years.. and still I wonder whether I will be fed!
