On one occasion the eccentric yogin, Tangtong Gyalpo, thought by many to be quite mad, said to a group of workmen engaged in a building project:

All straight isn’t straight.

A fool’s straight is crooked.
All crooked isn’t crooked.
A wise man’s crooked is straight.
All benefit isn’t benefit.
A fool’s benefit is harm.
All harm isn’t harm.
A wise man’s harm is benefit
All pleasure isn’t pleasure.
A fool’s pleasure is suffering.
All suffering isn’t suffering.
A wise man’s suffering is pleasure.
