In this talk, we will undertake a careful study of selected sūtras from the Yoga Sūtras, which are of particular importance in understanding the central ideas of the text as a whole. Patañjali introduces his readers to a complex range of philosophical precepts that form a basis for the forms of yoga practice he advocates. Using the selected sūtras as a point of entry, we will review some of those points of philosophy and consider how such ideas are related to the practical instructions included in the Yoga Sūtras. Handouts of the sūtras to be considered will be emailed to participants beforehand.
