PB Letters to Colleagues (Excerpts)

Primarily made up of excerpts copied from letters that PB wrote, not all of which were mailed, which usually contain philosophical content. The majority of the letters appear to be written before the publication of The Wisdom of the Overself, and include a letter from PB to himself, as well as one to Alan Watts. One of the letters at the end was published in The Mountain Path, which is from 1971.
