The adorable one who is seated
In the heart rules the breath of life.
Unto him all the senses pay their homage.
When the dweller in the body breaks out
In freedom from the bonds of flesh,
What remains? For this Self is supreme!
We live not by the breath that flows in
And flows out, but by him who causes the breath
To flow in and flow out.
–The Katha Upanishad
Death as Teacher
Eknath Easwaran translation
