PTS: A i 8
I,v,7
Mudu Sutta: Soft
translated from the Pali by
Thanissaro Bhikkhu

"Just as, of all trees, the balsam is foremost in terms of softness and pliancy, in the same way I don't envision a single thing that, when developed & cultivated, is as soft & pliant as the mind. The mind, when developed & cultivated, is soft & pliant."
