究竟窮極     Investigate until you are completely empty

不存軌則     And no discipline remains to follow

契心平等     The mind in accord is in perfect sameness

所作倶息     Where all effort ceases

狐疑盡淨     All doubts vanish completely

正信調直     The true faith is straightened out

一切不留     Not a single division remains

無可記憶     No memories at all retained

虚明自照     Empty, bright, shining

不勞心力     No exertion by the mind

非思處量     This is a place no thought can measure

識情難測     Knowledge and senses can scarcely fathom

Penetrate into the ultimate truth of mind
And we have neither things nor non-things
Enlightened and not enlightened—they are the same
Neither mind nor thing there is
– Dhritaka, the sixth Buddhist patriarch (Suzuki, 1949, p. 172)

‘O Saichi, tell us what kind of flavour is the flavour of Namu-amida-butsu,
Tell us what kind of flavour is the flavour of Namu-amida-butsu’
‘The flavour of Namu-amida-butsu is
A joy filling up the bosom
A joy filling up the liver
Like the rolling swell of the sea
No words—just the utterance: Oh, Oh!’
– Saichi (Suzuki, 1957, p. 174)

At one stroke I have forgotten all knowledge!
There’s no need for artificial discipline
At all times I manifest the ancient Way
And never fall into quietism

Wherever I walk I leave no footprint
My senses unrestrained by rules of conduct
In the ten quarters, all who have realized this truth
Declare it to be the highest
– Hsiang-yen (Suzuki, 1949, p. 243)

The mind moveth with the ten thousand things
Even when moving, it is serene
Perceive its essence as it moveth on
And neither joy nor sorrow there is
– Manura, the twenty-second Buddhist patriarch (Suzuki, 1949, p. 172)

The voice of him that crieth in the wilderness,
Prepare ye the way of the LORD;
Make straight in the desert a highway for our God.
Every valley shall be exalted,
And every mountain and hill shall be made low,
And the crooked shall be made straight,
And the manifold places plain,
And the glory of the LORD shall be revealed,
And all flesh shall be seen as one,
For the mouth of the LORD hath spoken.
The voice said, Cry.
And he said, What shall I cry?
All flesh is grass,
And all the goodliness thereof is as the flower of the field.
The grass withereth, the flower fadeth,
Because the spirit of the LORD bloweth upon it.
Surely the people are grass.
The grass withereth, the flower fadeth,
But the word of our God shall stand for ever.
(Isaiah 40)

It’s a feeling of complete ‘at-oneness’ with everything
It’s a feeling of ‘no-other-ness’
It’s a feeling of very profound peace
Even though there’s activity, you see no action
Everything just is
The very top state is one of very profound peace
– Lester Levenson, “Experiencing Truth” https://youtu.be/fAMBVE1cElM

Quicker than the blink of an eye one sees through the mundane and witnesses the sublime. Realization is now. Why worry about gray hair?
– Bodhidharma, “Breakthrough Sermon”
