Thanissaro Bhikkhu (Geoffrey DeGraff) is an American Buddhist monk of the Kammatthana (Thai Forest) Tradition. After graduating from Oberlin College in 1971 with a degree in European Intellectual History, he traveled to Thailand, where he studied meditation under Ajaan Fuang Jotiko, himself a student of the late Ajaan Lee. He ordained in 1976 and lived at Wat Dhammasathit, where he remained following his teacher’s death in 1986. In 1991 he traveled to the hills of San Diego County, USA, where he helped Ajaan Suwat Suvaco establish Metta Forest Monastery. He was made abbot of the Monastery in 1993.

… he should put forth extra desire, effort, diligence, endeavor, relentlessness, mindfulness, & alertness for the abandoning of those very same evil, unskillful qualities. Just as when a person whose turban or hair is on fire

O, that I might live for the interval that it takes to swallow having chewed up one morsel of food!

He doesn’t assume consciousness to be the self, or the self as possessing consciousness, or consciousness as in the self, or the self as in consciousness.
