Mystics, Ascetics, and Saints of India 
A Study of Sadhuism, With an Account of the Yogis, Sanyasis, Bairagis, and Other Strange Hindu Sectarians

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In Chapter VIII./ the principal ascetic sects and their subdivisions are described, the Yogz’s, commonly called jogt’s, and the yoga system receiving especial attention. In Chapters IX. To XI. The reader is taken into the company of many sadhus I have known, and within the precincts of a few of the monasteries I have visited. Probably these last-named chapters may help to bring European readers into actual touch, as it were, with sadhuism as it exists to-day; and, if so, I shall not regret the time and the trouble, by no means inconsiderable, involved in collecting the particulars which I have embodied in them.
