This Publisher’s Note explains the purpose of this specific edition of Swami Vivekananda’s four yogas. While Vivekananda’s original works are already available in comprehensive English versions, this book offers a unique "condensed and retold" version by Swami Tapasyananda, designed for an easier and more accessible reading experience.

The text highlights the book's success, noting that its popularity led to two previous editions in 1979 and 1983, originally published by Sri Ramakrishna Math in Madras. By May 1987, the copyright was transferred to Advaita Ashrama in the Himalayas for this third edition. Ultimately, the note serves to justify the book's existence as a simplified guide and to acknowledge the administrative transition between publishers.
