According to traditional texts and beliefs of Indian siddha medicine, the imbalance of these elements brings about disease, pain, and suffering. To remedy the imbalance of these elements, there are various cures including exercises and diets, breathing techniques, yoga, meditation, and mudra. According to traditional texts, yoga and meditation are two of the most important tools used in the process of healing. Mudra, which consists of speaking to the winds, is used to cure by opening channels of yang and yin. Today, there are many schools of thought in India specializing in the study of sidebars. These schools of thought differ in practice and theory, but all of them have one thing in common - they believe that the body is connected to the universe, and that ill health can result from a breakdown in this connection. As a result, all practicing medicine, whether it is herbal medicine or Ayurvedic medicine, should be guided by the intuition of a wise teacher who has been an expert in the field for many years. These teachers are called sidebars, and there are currently no fewer than fifteen siddhars in India today. In the early twentieth century, a young scientist named Ambe Ghandi was studying plant physiology when he realized that the way different plants differed from one another depended on the existence or absence of one principle, known as the unity principle. Unity principle means that living entities, for example plants and animals, are made up of parts that were once a single entity. This led him to apply this concept to various medical disorders. Together with Prabhas Patanjali and his students, he developed the siddhi system, which was later to become the foundation of modern medical science. With the development of modern technology, research in the field of medical science has also benefited from the siddha system, and modern medicines based on the siddha system are available almost everywhere, although earlier, the acceptance of these medicines was much slower in the western world.
