>Hello
Greetings. I sense your mind is troubled. Tell me of your troubles.
>Why conquer?
Why do you think conquer?
>One school might argue that it is a necessity of life
Form is emptiness, and emptiness is form.
>Conquer life, and life conquers us
The reverse side also has a reverse side.
>Submit to life, and life submits to us
When you're enlightened, every word is wisdom.
>Amen
Random talk is useless.
>Amen
The reverse side also has a reverse side.
>Random talk is useless
Form is emptiness, and emptiness is form.
