Steeped Horsehair
by The Brother in Mark 13 : 13¹

Mind is a disease of semen.
All that a man is or may be is hidden therein.
Bodily functions are parts of the machine; silent,
   unless in dis-ease.
But mind, never at ease, creaketh "I".
This I persisteth not, posteth not through genera-
   tions, changeth momently, finally is dead.
Therefore is man only himself when lost to himself
   in The Charioteering.

¹ also Matthew 10 : 22 and 24 : 13

Katha Upanishad

Know the Self as lord of the chariot,
The body is the chariot itself,
The discriminating intellect as charioteer,
And the mind as reins.
The senses, say the wise, are the horses;
Selfish desires are the roads they travel.
When the Self is confused with the body,
Mind, and senses, they point out, he seems
To enjoy pleasure and suffer sorrow.

When one lacks discrimination
And his mind is undisciplined, the senses
Run hither and thither like wild horses.
But they obey the rein like trained horses
When one has discrimination and has made
The mind one-pointed. Those who lack
Discrimination, with little control
Over their thoughts and far from pure,
Reach not the pure state of immortality
But wander from death to death; but those
Who have discrimination, with a still mind
And a pure heart, reach journey's end,
Never again to fall into the jaws of death.
With a discriminating intellect
As charioteer and a trained mind as reins,
They attain the supreme goal of life
To be united with the Lord of Love.
