In the 1970s, Ajahn Brahm began writing his own translation of and commentary on the Vinaya in order to support his fellow, Western monks who, at the time, lacked such a resource in English.

Ajahn Geoff eventually picked up the project and took it in his own direction (resulting in the now-famous BMC), but these original notes remain a solid resource for practical vinaya, alongside Bhante Suddhaso’s more recent translation of the Vibhaṅga.
