The Book In Ayurvedic classics the term Srotas is used as dynamic inner transport system of body-mind-spirit organization in addition to circulatory system. Ayurvedic classics proclaim “Srotomayam hi shariram” means that living body is a channel system and/or is comprised of innumerable channels which are designed as inner transport system for divergent function, gross and subtle, biological and energetic. Body-mind-spirit organization has as many as Srotamsi the number of life factors operating in the life process- Yawantah Purushe Murtimanto Bhavavisheshah Tavantevasmin Srotasam Prakara Visheshah. Ayurvedic Acharyas have described that the entire range of life processes in health and disease depends on integrity of the srotas system. Understanding the concept of Srotamsi and Srotovaiguny facilitates the Vaidya to take decisions accurately with respect to treatment and prognosis. There are many facts about Srotas in meaning the structure through which the Sravanam Kriya takes place. Sushruta has described very well about the number, kinds and functions of Srotas in context of Srotovidddha Laxanas (symptoms of injury). The Srotas, in the broad term, refers to the channels of circulation present in human body. Present day scholars of Ayurveda are not unanimous in identifying srotas in its structure and function. This is so because of difference in description present in Sushruta Samhita, Charaka Samhita, Ashtanga Samgraha, Ashtanga Hridaya and their commentaries. Modern scholars like Gananath sen, B.G. Ghanekar, C. Dwarakanath and others have interpreted their own way. The main aim of this book is to study the concept of Srotas from various Ayurvedic classics and it correlates with modern anatomy. The literary material related to Srotas has been collected from different Ayurveda Samhitas and modern anatomy books. Critically reviewed and correlated with modern terms. Keeping in mind, both the ancient and modern knowledge.
