Coolness

“Mendicants, a mendicant with six qualities can’t realize supreme coolness.
What six?
It’s when a mendicant doesn’t keep their mind in check when they should. They don’t exert their mind when they should. They don’t encourage the mind when they should. They don’t watch over the mind with equanimity when they should. They have bad convictions. They delight in identity.
A mendicant with these six qualities can’t realize supreme coolness.
