Samkhya philosophy is based on the idea that the universe is composed of two fundamental principles: Purusha (consciousness) and Prakriti (matter). Prakriti is further composed of three Gunas (qualities): Sattva (purity), Rajas (activity), and Tamas (inertia).

Purusha is the conscious principle of the universe. It is pure consciousness and is not affected by the changes of Prakriti.

Prakriti is the material principle of the universe. It is the source of all matter and is responsible for the changes and transformations of the universe.

The three Gunas of Prakriti are Sattva (purity), Rajas (activity), and Tamas (inertia). These Gunas are responsible for the different qualities and characteristics of matter.

Sattva is the Guna responsible for purity, clarity, and illumination. It is associated with knowledge, wisdom, and spiritual development.

Rajas is the Guna responsible for activity, passion, and restlessness. It is associated with desire, ambition, and ego.

Tamas is the Guna responsible for inertia, dullness, and ignorance. It is associated with laziness, apathy, and delusion.

The goal of Samkhya philosophy is to achieve liberation from the cycle of birth and rebirth, to attain union with the divine, and to experience the highest state of consciousness.

According to Samkhya philosophy, liberation can be achieved by cultivating knowledge and wisdom. This involves understanding the true nature of reality and the distinction between Purusha and Prakriti.

The Samkhya Karika is a collection of aphorisms summarizing the teachings of Samkhya philosophy. It is attributed to the sage Ishvara Krishna and is considered to be one of the most important texts in Samkhya philosophy.

Kapila is considered to be the founder of Samkhya philosophy. He is said to have lived in ancient India around the 6th century BCE.

Samkhya philosophy is considered to be the foundation of Yoga philosophy. Yoga philosophy incorporates the principles of Samkhya philosophy and adds the concept of Ishvara (God) and the practice of yoga as a means to achieve liberation.

Atman is a concept in Vedanta philosophy, not Samkhya philosophy. Atman refers to the individual self or soul.

According to Samkhya philosophy, the ultimate reality is Purusha, the conscious principle. Purusha is pure consciousness and is not affected by the changes of Prakriti.

According to Samkhya philosophy, there are infinite Purushas. Each Purusha is an individual conscious entity.
