The Samkhya Sutras posit the existence of two fundamental realities: Purusha (consciousness) and Prakriti (matter). Purusha is pure consciousness, unchanging and inactive, while Prakriti is the material cause of the universe, consisting of three gunas (qualities): sattva, rajas, and tamas.

Purusha is pure consciousness, the unchanging and inactive principle that serves as the witness to all experience. It is distinct from Prakriti, the material cause of the universe, and is characterized by its self-awareness and luminosity.

Prakriti is the material cause of the universe, consisting of three gunas (qualities): sattva (purity, luminosity), rajas (activity, passion), and tamas (inertia, darkness). Prakriti is the source of all material phenomena and is responsible for the evolution of the universe.

Purusha is the witness, the unchanging and inactive principle that observes the workings of Prakriti. Prakriti is the experienced, the material cause of the universe that undergoes transformation and evolution. Purusha and Prakriti are distinct and independent entities, but their interaction gives rise to the phenomenal world.

Prakriti evolves into the phenomenal world through the interaction and transformation of its three gunas: sattva, rajas, and tamas. The gunas combine in various proportions to give rise to different material elements and qualities, leading to the manifestation of the diverse phenomena we experience.

Purusha, being pure consciousness, is unaffected by the evolution of Prakriti. It serves as a witness to the unfolding of the material world, remaining detached and unchanged throughout the process.

The ultimate goal of the Samkhya philosophy is to achieve liberation from suffering (duhkha). This is accomplished through the realization of the true nature of Purusha, the unchanging and pure consciousness, and its distinction from Prakriti, the material cause of suffering. By gaining this knowledge, one can transcend the limitations of the material world and attain a state of liberation.

Asmita is the sense of self, the mistaken identification of the self with the products of Prakriti, such as the body, mind, and intellect. This false identification leads to attachment, suffering, and the perpetuation of the cycle of rebirth. The realization of the true nature of Purusha, as distinct from Prakriti, is essential for overcoming asmita and achieving liberation.

Avidya is ignorance of the true nature of reality, the fundamental misconception that leads to suffering and the perpetuation of the cycle of rebirth. This ignorance includes the mistaken identification of the self with Prakriti, the attachment to material objects, and the belief in the reality of the phenomenal world. Overcoming avidya through knowledge and discrimination is essential for achieving liberation.

Moksha is liberation from suffering, the ultimate goal of the Samkhya philosophy. This liberation is achieved through the realization of the true nature of Purusha, the unchanging and pure consciousness, and its distinction from Prakriti, the material cause of suffering. By gaining this knowledge, one can transcend the limitations of the material world and attain a state of liberation, characterized by the cessation of suffering and the attainment of lasting happiness.

Viveka is the discrimination between Purusha and Prakriti, the ability to distinguish between the unchanging and pure consciousness of Purusha and the changing and material nature of Prakriti. This discrimination is essential for overcoming avidya (ignorance) and achieving liberation. By developing viveka, one can recognize the true nature of reality and transcend the limitations of the material world.

Kaivalya is isolation from the world, the state of liberation in which the individual soul (Purusha) is completely detached from Prakriti and its products. In this state, the soul is no longer subject to the cycle of rebirth and suffering and experiences pure consciousness and bliss. Kaivalya is the ultimate goal of the Samkhya philosophy and is achieved through the realization of the true nature of Purusha and the discrimination between Purusha and Prakriti.

Gunas are the three fundamental qualities of Prakriti, the material cause of the universe. These qualities are sattva (purity, luminosity), rajas (activity, passion), and tamas (inertia, darkness). The gunas combine in various proportions to give rise to different material elements and qualities, leading to the manifestation of the diverse phenomena we experience.

Prakriti-laya is the dissolution of Prakriti, the material cause of the universe. This dissolution occurs when the gunas (qualities) of Prakriti are completely balanced and in equilibrium. In this state, Prakriti ceases to manifest the phenomenal world, and Purusha, the pure consciousness, remains alone. Prakriti-laya is the ultimate goal of the Samkhya philosophy, as it leads to the liberation of Purusha from the cycle of rebirth and suffering.

Purusha-darshana is the vision of Purusha, the pure consciousness. This vision is achieved through the realization of the true nature of reality, which involves discriminating between Purusha and Prakriti and understanding their distinct characteristics. Purusha-darshana leads to liberation from suffering and the attainment of kaivalya, the state of isolation from the world and pure consciousness.
