The present book has been specially designed by the author keeping in mind the needs of the students of yoga in europe and america , who need a pratical but non-technical presentation of the subject in a language which is accessible to the beginner in the path. We hope the book will amply serve this most sacred purpose in view.
As a great saint and philosopher , his spotless purity, saintliness of life, magnetic and voluminous writings were unparalleled in record ;he was not only an eminent and popular author of hindu religious and philosophical subjects, but in an authority on those subjects.
