|Master Kyong Ho|
A man of deep roots and great wisdom is different. As soon as he hears a kung-an he establishes his mind like a mountain and settles his mind like the sea. He keeps only the hau-t'ou raised before him as if he were deaf or dumb. Since he has not yet been able to understand the reiterated instructions of the Buddhas and Patriarchs, he cannot but have a doubt. He is constantly doubting and constantly probing as if trying to save his burning head. Suddenly one morning he shouts "Ha!" and heaven and earth are overturn. He enters into a place unfathomable by others, and after a laugh alone, he only smiles. When he has reached that stage he can taste for himself without one iota of difference, the flavor of the sincere words of the Buddda and Patriarchs.
