Raja Yoga is a spiritual practice that aims to achieve union with the divine through the control of the mind and body.

The eight limbs of Raja Yoga are Yama (moral restraints), Niyama (observances), Asana (postures), Pranayama (breath control), Pratyahara (withdrawal of the senses), Dharana (concentration), Dhyana (meditation), and Samadhi (enlightenment).

Yama and Niyama are the first two limbs of Raja Yoga and are considered to be the foundation of ethical conduct and self-discipline. They include principles such as non-violence, truthfulness, non-stealing, moderation, and cleanliness.

Asana is the third limb of Raja Yoga and refers to physical postures. The purpose of Asana is to improve physical health and flexibility, as well as to prepare the body for meditation.

Pranayama is the fourth limb of Raja Yoga and refers to breath control. The purpose of Pranayama is to control the breath and regulate the flow of prana, or life force, in the body.

Pratyahara is the fifth limb of Raja Yoga and refers to the withdrawal of the senses from external objects. The purpose of Pratyahara is to turn the attention inward and focus on the inner world.

Dharana is the sixth limb of Raja Yoga and refers to concentration. The purpose of Dharana is to concentrate the mind on a single object, such as the breath, a mantra, or a visualization.

Dhyana is the seventh limb of Raja Yoga and refers to meditation. The purpose of Dhyana is to achieve a state of deep meditation, in which the mind is focused and absorbed in the object of meditation.

The ultimate goal of Raja Yoga is to achieve union with the divine, or Brahman, the ultimate reality. This is achieved through the practice of the eight limbs of Raja Yoga, which lead to a state of Samadhi, or enlightenment.

Bhakti Yoga, Karma Yoga, and Jnana Yoga are all paths of yoga that lead to union with the divine. Hatha Yoga, on the other hand, is a system of physical postures and breathing exercises that is often used as a preparatory practice for Raja Yoga.

Patanjali is considered to be the founder of Raja Yoga. He is the author of the Yoga Sutras, a seminal text on Raja Yoga that outlines the eight limbs of the practice.
