汾陽無德禪師語錄 1.105

1.105

「啐啄同時用最難，相逢恰似兩風顛，栽松切囑超今古，普化當時得用全。」

"Simultaneous pecking from within and without is the hardest function;
When meeting, they are just like two madmen.
Planting pine trees, he earnestly enjoined transcendence of past and present;
Puhua at that time attained the complete functioning."
