For thousands of years the secrets of Yoga have been handed down from the Guru to capable disciples by word of mouth or by transmission of energy. This ancient tradition of imparting secret lore and practices from the adept to qualified students is called “Guru-Shishya-Parampara”, the Great Heritage originating from the teachings of Lord Shiva. It is of immense significance especially in Tantrism, of which Hatha- and Kundalini-Yoga are important and basic aspects, but found its expression also in classical Indian arts like music and dance. If a student is eager to fit into this divine line of master and disciple he needs special aptitude and eagerness to qualify for initiation into the mysteries of Yoga.
