Critical study of the manuscript Yogasudhanidhi

Background: The knowledge gained by ancient seers of Ayurveda was passed down from generation to generation through manuscripts. The scientific and structured study of manuscripts is called Manuscriptology. Understanding scripts, languages, writing tools, and the conservation, preservation, and maintenance of manuscripts is essential. The study of medical manuscripts, their constraints, and the strategies to validate the concepts, drugs, diseases, treatments, and applications in the field of medical science is highly valuable. The manuscript Yogasudhanidhi, which is available in the form of a paper script, with 64 folios, written in Devanagari script, authored by Vandi Mishra, MSS No. 1391, was collected from The Adyar Library and Research Centre, Chennai, for this study. Objectives: The present study aims to transcribe, translate, and critically analyze the contents of the manuscript Yogasudhanidhi and compare them with relevant prakaranas (sections) of Ashtanga Hridaya. Materials and methods: An exploratory study of the manuscript was conducted, followed by transcription and translation into English. Then, critical analysis and comparison with Ashtanga Hridaya were performed. Results: The manuscript Yogasudhanidhi comprises four chapters, namely Balaposhana (care of children), Balaroga cikitsa (treatment of pediatric diseases), Bala stri kumaradinam samanya cikitsa (general treatment of childhood disorders) and Balagrahabalidanadi (management of infantile afflictions). Thus, it describes the management of newborns and different pediatric diseases briefly. It focuses exclusively on the most effective formulations from various classical sources in treatment. Yogasudhanidhi gives more importance to offerings and prayers. Many mantras (hymns) are advised for a child, to attain lifespan and strength and many pujas (ritual worship) like narayana puja, karthikeya puja etc. are explained for the well-being of the child. Conclusion: The detailed understanding of the manuscript Yogasudhanidhi enhances the theoretical and practical knowledge in the field of Kaumarabhritya (Ayurvedic pediatrics) and thus Ayurveda.
