I think it is worth reminding folks that these 7 documents are the results of many years of work to bring the knowledge they hold. Paul here presents in his own style, utilizing terminology that for some will require a dictionary, a very thorough rendering of these plants, preparations, substances and spiritual activity. They are, however, eminently readable.
For the commentary on Lecture 5 we created separate documents for each of the plants/preparations and the introduction. They are available from the archive index or here by clicking on the title.
