The Yogasutras are one of the most important works of Indian culture, and constitute the foundational text of Yoga. An attempt to interpret the Yogasutras based on some special criteria: (1) To use the traditional commentaries as auxiliaries, not as guides, (2) To interpret those sutras which Patanjali anaysis real phenomena, (3) To adhere to a unitary and singular meaning for the technical terms of Patanjali, and (4) To adhere also to the definitions given by Patanjali.
