Carbons 17 (Notebooks)

Contains all 28 Old Categories, with selections from all the Grey Long files, most or all of the Vinyl files, PB Replies, Talks in the Orient, and Carbons 7 (9th and 10th series). A reference to Frederic Spiegelberg's 1962 book "Spiritual Practices of India," the quality of the paper, and PB's relatively youthful handwriting suggest it was assembled some 20 years before his death.
