ting all diseases if the involved movements of Vāta and Pitta are free from 18 faults. It thus contains something new which is not found in the previous works.
All the other 6 works in this collection are in either Hindi or in its source the Eastern Rajasthani. The first of them, which is in prose, purports to be the Gorakşa Upanişad, which is however probably a Hindi rendering of the Sanskrit work of that name mentioned in Aufrecht's Catalogue and utilised in the GSS. for supporting some parts of the Siddhānta expounded therein. The remaining 5 works are only popular songs showing that physical renunciation was considered essential by the votaries of this sect in the period between 801 to 1500 A.D., to which the language thereof seems to belong.
I regret to have noticed some misprints in the said Sanskrit works. I understand that they have remained uncorrected because Dr. Kalyani was required to entrust the work of proofcorrection to another person on account of her illness and am assured that a list of corrections will be inserted before the copies of the book are bound up. Lastly, I should not fail to refer to the enterprise of Sri D. K. Gondhalekar, whose Poona Oriental Book House undertook to publish this work and make its copies available to those interested in the literature of the Nātha Yogis at his own cost. As much credit is due to him for doing so as to the learned elitress who made the collection and prepared its press-copy.
