The Samkhya-Yoga theory posits that reality consists of two fundamental principles: Purusha (consciousness) and Prakriti (matter). These two principles are distinct and independent, and their interaction gives rise to the phenomenal world.

Prakriti is the material cause of the universe, meaning that it is the substance from which all physical objects are made. It is composed of three gunas (qualities): sattva (purity), rajas (activity), and tamas (inertia).

Purusha is the conscious principle of the universe, meaning that it is the source of consciousness and awareness. It is pure consciousness, devoid of any qualities or attributes.

The interaction between Purusha and Prakriti gives rise to the phenomenal world through the process of evolution. This process involves the unfolding of Prakriti's potential into the various forms of the material world.

The ultimate goal of the Samkhya-Yoga theory is to achieve liberation from the cycle of birth and rebirth (moksha). This is achieved through the realization of the true nature of reality and the separation of Purusha from Prakriti.

Sattva, rajas, and tamas are the three gunas (qualities) of Prakriti. Dharma is not a guna.

According to the Samkhya-Yoga theory, karma is the cause of suffering. Karma is the sum of one's actions and intentions, and it determines the nature of one's future experiences.

According to the Samkhya-Yoga theory, liberation from the cycle of birth and rebirth can be achieved by gaining knowledge of the true nature of reality. This knowledge leads to the realization of the separation of Purusha from Prakriti and the cessation of suffering.

Purusha, Prakriti, and Gunas are key concepts in the Samkhya-Yoga theory. Maya is not a key concept.

Yoga is a means to achieve liberation in the Samkhya-Yoga theory. It is a set of practices that help to control the mind and senses, leading to the realization of the true nature of reality.

Raja Yoga, Karma Yoga, and Jnana Yoga are types of yoga mentioned in the Samkhya-Yoga theory. Bhakti Yoga is not mentioned.

The ultimate goal of Raja Yoga is to control the mind and senses. This is achieved through the practice of meditation and other yogic techniques.

The ultimate goal of Karma Yoga is to perform selfless actions. This means performing actions without attachment to the fruits of those actions.

The ultimate goal of Jnana Yoga is to gain knowledge of the true nature of reality. This is achieved through the study of scriptures, reflection, and meditation.
