Samkhya is one of the earliest schools of Indian philosophy and most systems, including yoga, have been drawn from or influenced by it. Samkhya is a dualisitic philosphy and postulates two eternal realities: Purusha,the witnessing consciousness and Prakriti, the root cause of creation, composed of three gunas. This text highlights the unique contribution of Samkhya philosophy in man’s quest to understand his true nature. It discusses the pratical theories of causation, manifestation, bondage and liberation. For the spiritual aspirant, Samkhya is the metaphysics of self-realization and yoga is the sadhana or means to achieve it. Samkhya Darshan contains the full Sanskrit text of Ishvara Krishna’s „Samkhya Karika“ as well as tranasliteration and translation.
