This meditation was adapted by Thanissaro Bhikkhu the Abbott of the Metta Forest Monastery near San Diego. He learned this from his Thai teacher Ajaan Fuang who learned this technique from Ajaan Lee Dhammadharo (1907-1961).  I learned it from my teacher, Pat Coffey, and now it is yours!

Thich Nhat Hahn:“Breath is the bridge which connects life to consciousness, which unites your body to your thoughts. Whenever your mind becomes scattered, use your breath as the means to take hold of your mind again.”
