Emptiness is the fasting of the mind.

At the end of the fast, I felt physically tired, but mentally stronger. In functioning without something my body relied on, I had broken a limit that existed in my mind. I gained flexibility and adaptability and resourcefulness. That experience with fasting bled into the rest of my life. Fasting is a physical challenge driven by the intellect. Being silent for long periods of time brought up completely different issues–who was I when I detached from other people?

The empty-mindedness of chi sao applies to all activities we may perform, such as dancing. If the dancer has any idea at all of displaying his art well, he ceases to be a good dancer, for his mind stops with every movement he goes through. In all things, it is important to forget your mind and become one with the work at hand. When the mind is tied up, it feels inhibited in every move it makes and nothing will be accomplished with any sense of spontaneity. The wheel revolves when it is not too tightly attached to the axle. When it is too tight, it will never move on. As the Zen saying goes: “Into a soul absolutely free from thoughts and emotion, even the tiger finds no room to insert its fierce claws.” In chi sao the mind is devoid of all fear, inferiority complexes, viscous feeling, etc., and is free from all forms of attachment, and it is master of itself, it knows no hindrances, no inhibitions, no stoppages, no clogging, no stickiness. It then follows its own course like water; it is like the wind that blows where it lists.

If man has nothing to eat, fasting is the most intelligent thing he can do. If, for instance, Siddhartha had not learned to fast, he would have had to seek some kind of work today, either with you, or elsewhere, for hunger would have driven him. But as it is, Siddhartha can wait calmly. He is not impatient, he is not in need, he can ward off hunger for a long time and laugh at it. Therefore, fasting is useful, sir.

When the mind is satisfied, that is a sign of diminished faculties or weariness. No powerful mind stops within itself: it is always stretching out and exceeding its capacities. It makes sorties which go beyond what it can achieve: it is only half-alive if it is not advancing, pressing forward, getting driven into a corner and coming to blows; [B] its inquiries are shapeless and without limits; its nourishment consists in [C] amazement, the hunt and [B] uncertainty,20 as Apollo made clear enough to us by his speaking (as always) ambiguously, obscurely and obliquely, not glutting us but keeping us wondering and occupied.21 It is an irregular activity, never-ending and without pattern or target.

Fasting

By Mevlana Jelaluddin Rumi
(1207 - 1273)

English version by Coleman Barks

There's hidden sweetness in the stomach's emptiness.
We are lutes, no more, no less. If the soundbox
is stuffed full of anything, no music.
If the brain and belly are burning clean
with fasting, every moment a new song comes out of the fire.
The fog clears, and new energy makes you
run up the steps in front of you.
Be emptier and cry like reed instruments cry.
Emptier, write secrets with the reed pen.
When you're full of food and drink, Satan sits
where your spirit should, an ugly metal statue
in place of the Kaaba. When you fast,
good habits gather like friends who want to help.
Fasting is Solomon's ring. Don't give it
to some illusion and lose your power,
but even if you have, if you've lost all will and control,
they come back when you fast, like soldiers appearing
out of the ground, pennants flying above them.
A table descends to your tents,
Jesus' table.
Expect to see it, when you fast, this table
spread with other food, better than the broth of cabbages.

The mind must be given relaxation — it will rise improved and sharper after a good break. Just as rich fields must not be forced — for they will quickly lose their fertility if never given a break — so constant work on the anvil will fracture the force of the mind. But it regains its powers if it is set free and relaxed for a while. Constant work gives rise to a certain kind of dullness and feebleness in the rational soul.” — SENECA, ON TRANQUILITY OF MIND,

Quieting the mind means less regretting. The mind is still when it is totally here and now in perfect oneness with the action and the actor. It is the purpose of the Inner Game to increase the frequency and the duration of these moments, quieting the mind by degrees and realizing thereby a continual expansion of our capacity to learn and perform.

What is meditation? What is leaving one's body? What is fasting? What is holding one's breath? It is fleeing from the self, it is a short escape of the agony of being a self, it is a short numbing of the senses against the pain and the pointlessness of life. The same escape, the same short numbing is what the driver of an ox-cart finds in the inn, drinking a few bowls of rice-wine or fermented coconut-milk. Then he won't feel his self any more, then he won't feel the pains of life any more, then he finds a short numbing of the senses. When he falls asleep over his bowl of rice-wine, he'll find the same what Siddhartha and Govinda find when they escape their bodies through long exercises, staying in the non-self.

A mind perpetually open, will be a mind perpetually vacant!
العقل المنفتح على الدوام هو عقل فارغ على الدوام!

A mind too active is no mind at all. — Infirmity

The unfed mind devours itself.

A heart pulsating in harmony with the circulation of sap and the flow of rivers? A body with the rhythms of the earth in its movements? No. Instead: a mind, shut off from the oxygen of alert senses, that has wasted itself on 'treasons, stratagems and spoils' — of importance only within four walls. A tame animal — in whom the strength of the species has outspent itself, to no purpose.

There is nothing mind can do that cannot be better done in the mind's immobility and thought-free stillness.

When mind is still, then truth gets her chance to be heard in the purity of the silence.
