The limbs of yoga are all of the implementations of the practice. And they are also described by Patañjali as upāya or remedy for flagging practice (YS II.26).

This first limb is something of an exception to the seemingly optional nature of the limbs as Patañjali describes it as a universal obligation. Why? The first limb, Yama, is concerned with the creation of a safe space for people. A failure to create such a safe space would render the practice of Yoga impossible.
