The Samkhya school believes that the universe is composed of two fundamental principles: Prakriti (nature) and Purusha (consciousness).

Prakriti is the material cause of the universe, from which all physical objects are made.

Purusha is the conscious principle of the universe, which is responsible for consciousness and experience.

Prakriti and Purusha are mutually dependent, as Prakriti provides the material for Purusha's experience, and Purusha provides the consciousness for Prakriti's activity.

The goal of the Samkhya school is to achieve moksha (liberation), which is the state of complete freedom from suffering and the cycle of birth and rebirth.

According to the Samkhya school, suffering is caused by attachment to sense objects, ignorance of the true nature of reality, and karma (the law of cause and effect).

The path to moksha (liberation) according to the Samkhya school is the path of knowledge (jnana yoga), which involves gaining knowledge of the true nature of reality and the distinction between Prakriti and Purusha.

Kapila is considered to be the founder of the Samkhya school.
