Prakriti, a significant concept in the Bhagavad Gita and broader Sanskrit literature, is derived from the ancient language of Sanskrit, where it refers to 'nature' or 'primal motive force.' It is often associated with the material realm, embodying the physical universe including our bodies and minds.

In the context of the Bhagavad Gita, a key philosophical text within the Mahabharata, Prakriti is portrayed as the primeval matter subjected to elemental influences, responsible for all forms and entities in the material world. It covers all qualities such as transparency, activity, and lethargy. It's often referred to as the manifest aspect of existence, the feminine principle of the universe that toils together with Purusha, or the unmanifest & transcendent element, often defined as the masculine principle.

The interplay between Prakriti and Purusha forms a pivotal point in the philosophy of the Bhagavad Gita. Here, Prakriti is described as the field, while Purusha is the perceiver and interpreter of the field. This interrelationship sets life's dynamics, which encompasses physical, mental, and spiritual realms.

Interestingly, Krishna in the Bhagavad Gita says that there are two types of Prakriti: the perishable and the imperishable. The perishable consists of all living beings in the world, while the imperishable Prakriti, represents the eternal being that prevails and exists beyond the temporal and spatial limitations.

In summary, Prakriti in the Bhagavad Gita and Sanskrit literature corresponds to the physical nature and inherent qualities that guide our actions and reactions in this world. It symbolizes the ever-changing, dynamic reality that envelops us, guided by the silent and watchful Purusha.
