Among the various forms of Sanskrit literature, one is sutra. Generally, works in the form of sutra (sutra-rupa-grantha), are considered source works (mula-grantha), and present a particular subject matter. They are often descriptive in nature, like the Sankhya Sutras (which are not extant) which present the Sankhya’s school of philosophy, the Vyakarana Sutras that present grammar (vyskarasam) using a meta language, the Vaisesika Sutras, and the Yoga Sutras. These sutras form one group i.e. they are descriptive and present a given subject matter.
