"Yes, there is
That which is the end of understanding.
Yes, there is
That which you will only understand
At the minds flowering time,
When she shall leaf and bud and burst
Into her fullest inflorescence of fine flowers.
But should you try to trammel up the mind
And bind her, confine her, and strive to turn her inwards
You will not understand.

For there is a power of the minds prime
Which, rising like the sun in all her majesty,
Shines forth with rays of thought at one with feeling.
Hold still the vision of thy Soul in purity
Freed from all else.
Let but thy little mind be empty of all things else;
All things save one thine aim
To reach the end of understanding,
For that subsists beyond the mind."

The Chaldean Oracle (Anon)
