This book deals with the digestive system in three sections. The first covers the physiology of digestion, the psychology of hunger and eating, and the ayurvedic and yogic view of digestion and food habits. The second section describes the patho-physiology and yogic management of a variety of digestive disorders from simple wind and indigestion to nagging acidity, annoying constipation and piles, distressing diarrhoea and dysentery, with special reference to diet. The third section deals with the yogic practices needed to remove digestive disorders and keep the digestive system in good health. Clear instructions and diagrams for each practice are given, which even a beginner can follow. The text was written by a qualified and experienced doctor in this field under the guidance of Swami Satyananda Saraswati.
