The spiritual path begins all noise and no signal.
Next, differentiate between signal and noise.
Then, work at making the signal stronger.
After that, work at reducing the noise.
The next, trickier step is to let signal and noise be and place the attention on the signal rather than the noise.
Then, allowing the noise to strengthen the signal—like the dark of night brings out the stars.
After that, there is no longer any difference between noise and signal, and the spiritual path ends—all signal, no noise.
And yet throughout, nothing has changed.
The ratio remains the same.
