The Synthesis of Yoga - Sri Aurobindo Ashram

918 The Synthesis of Yoga
In 1955, the Arya text of the Introduction, the 1948 text of Part I,
a text of Part II incorporating Sri Aurobindo’s revisions from Period 2,
and the Arya texts of the chapters comprising Part III and Part IV,
were published by the Sri Aurobindo International University Centre
as On Yoga I: The Synthesis of Yoga. (On Yoga II, published in 1958,
consisted of a selection of Sri Aurobindo’s letters on yoga.) The incomplete
chapter “The Supermind and the Yoga of Works” appeared
in this edition for the first time as chapter XIII of Part I. The SAIUC
edition was reprinted, with corrections, in 1957. The same publisher
(under the new name Sri Aurobindo International Centre of Education)
issued a new edition of the same text in 1965.
In 1970 The Synthesis of Yoga was published as volumes 20 and
21 of the Sri Aurobindo Birth Centenary Library. This edition was
reprinted many times.
The present edition has been thoroughly checked against all related
manuscripts and printed texts. Many typographical and other
errors have been corrected. The edition includes for the first time Sri
Aurobindo’s scattered revisions in the Introduction and substantial
revision of chapters XV – XVII of Part II. It is the first edition of the
book to include the text of “The Supramental Time Consciousness”,
the incomplete chapter Sri Aurobindo wrote for Part IV before setting
aside “The Yoga of Self-Perfection”.
