The Synthesis of Yoga - Sri Aurobindo Ashram

916 The Synthesis of Yoga
Chapters VII – XII. Extensively revised during Periods 2 and 3. The
typed sheets containing the later stages of the Period 2 revision of
chapters VII and VIII were misplaced before the start of Period 3,
obliging Sri Aurobindo to work on transcripts of the Arya pages containing
only the earlier stages of the revision. The unused versions from
Period 2 have since been found, and are reproduced in the reference
volume (volume 35).
Appendix: Chapter XIII. During Period 3, Sri Aurobindo wrote this
draft of a chapter meant to follow the last complete chapter of Part
I, but did not prepare it for publication in the 1948 edition of the
Synthesis. Found among his papers after his passing, it was published
for the first time in the 1955 edition of the book.
Around the same time that Sri Aurobindo worked on the chapter
published as “Appendix: Chapter XIII”, he produced several drafts of
a chapter entitled “The Yogic Consciousness and Works”, which he
also intended to place at the end of Part I. None of these drafts are
sufficiently well worked out to be published as part of the text of The
Synthesis of Yoga. The most important of them are reproduced in the
reference volume (volume 35).
Part II: The Yoga of Integral Knowledge
These twenty-eight chapters correspond to Arya chapters XIII – XL. Sri
Aurobindo revised eleven of these chapters during Periods 1 and 2, but
did not prepare any of them for publication. The Period 2 revision was
incorporated into the text of the 1955 edition; the Period 1 revision
was not discovered until the 1970s and appears in print for the first
time in the present edition.
