“Pendell's corner
The first bowl cleanly moistens my lips and throat;
The second banishes my loneliness;
The third chases through all dullness
To clarify every word I've ever read.
The fourth brings on a light sweat
That cleanses away life's troubles.
The fifth purifies my soul.
The sixth beckons me to the Immortals.
The seventh is my limit,
A light breeze breaks from my sleeves.
— Lu T'ung, "Song of Tea" (quoted in Pendell)
The second banishes my loneliness;
The third chases through all dullness
To clarify every word I've ever read.
The fourth brings on a light sweat
That cleanses away life's troubles.
The fifth purifies my soul.
The sixth beckons me to the Immortals.
The seventh is my limit,
A light breeze breaks from my sleeves.
