Yoga philosophy is based on Samkhya metaphysics that defines the language of yoga. Which is totally dualistic philosophy, accepting both consciousness and matter is real. Samkhya is one of the six major philosophies of India. Samkhya describes the full spectrum of human existence by revealing the basic elements that make up the macrocosm and the microcosm. Samkhya teaches us about the components of the body, mind, and spirit, from the gross elements that make up the physical body to the more subtle elements of the mind and consciousness. Samkhya names each element teaches us its function and shows us the relationship each element has to all others. It is effectively a map of the human being. And yoga is your vehicle that will take you to different locations in your map of body, mind, spirit. Which has a completely practical approach to have self-realization.
Patanjali later concluded in his work that there Is only one reality, that supreme is Ishvara, that Ishvara is Pranava (sound of om). Even though Patanjali accepts the whole metaphysics of Samkhya philosophy but later says that there is supreme consciousness. There Is only one reality, one truth from where every other thing emerges from. where it concludes that Patanjali system of yoga had a non-dualistic approach.
