As Justin Fornal find out, it turns out bark cloth is an ancient art. The Baganda of southern Uganda continue to utilize bark to create textiles from the mutuba tree. The bark is used to clothe the deceased, and is seen as having spiritual qualities. Witches and mediums wear the cloth. It is sustainable because the tree grows back the bark and you slather a resin over where you take off the bark.
These are the words that supposedly helped Bahiya find enlightenment:
In reference to the seen, there will be only the seen. In reference to the heard, only the heard. In reference to the sensed, only the sensed. In reference to the cognized, only the cognized. That is how you should train yourself. When for you there will be only the seen in reference to the seen, only the heard in reference to the heard, only the sensed in reference to the sensed, only the cognized in reference to the cognized, then, Bāhiya, there is no you in connection with that. When there is no you in connection with that, there is no you there. When there is no you there, you are neither here nor yonder nor between the two. This, just this, is the end of stress.
