TEXTUAL WORK : Textual Work of the P.L.R.D. can be Classified in the following heads :

A. EDITING OF UNPUBLISHED YOGA TEXTS: In order to widen the knowledge of Yoga, it is necessary to publish such Yoga Texts which have not yet been published and are still in the form of MSS.. In this connection the P.L.R.D. has the credit of editing the Text named Brhadyogiyajnavalkyasmrti. This Text was brought to light for the first time by this Department. The work on Satkarma Sangrah and Goraksha Shatakam is also of the same category.

B. CRITICAL EDITIONS OF YOGA TEXTS: Generally the published yoga texts are based on a single manuscript. Hence it is necessary to edit Yoga texts critically with the help of maximum available MSS. in order to provide authentic version of the texts. Our works of this nature are : (1) Hathapradipika (2) Gheranda Samhita (3) Siva Samhita.

C. RECONSTRUCTION OF EXTINCT YOGA TEXTS (proposed) : There are many Yoga Texts such as Devala Smriti , Harita Smriti etc. which are extinct today. However , we come across many references quoted in different scriptures on the name of such Texts. The Department is engaged in collecting such quotations from different Scriptures and after editing them properly , the revival of such extinct Yoga Texts can be made possible . In this connection we have collected references available on the names of Devala Smriti and Harita Smriti which are extinct now. We are trying to classify and arrange the collected material in order to give them the shape of complete Book.
