If you want to catch a rat
You don’t need a fancy cat
If you want to learn the principles
Don’t study fine bound books
The True Pearl’s in a hemp sack
The Buddha nature rests in huts
Many grasp the sack
But few open it.

Shide (Unknown-), Shide was a Tang Dynasty Chinese Buddhist poet at the Guoqing Temple on Mount Tiantai on the East China Sea coast
