Zen Master Seung Sahn - Three Letters to a Beginner

Good stuff from Seung Sahn, as always:

"Your before thinking mind, my before thinking mind, all people's before thinking minds are the same. This is your substance. Your substance, my substance, and the substance of the whole universe become one. So the tree, the mountain, the cloud and you become one. Then I ask you: Are the mountain and you the same or different? If you say 'the same,' I will hit you thirty times. If you say 'different,' I will still hit you thirty times. Why?"
