The Yoga School believes that the ultimate goal of human existence is to achieve liberation (moksha) from the cycle of birth, death, and rebirth (samsara). This liberation is attained through self-realization and the realization of the true nature of the Self.

The Yoga School identifies three main types of yoga: Jnana Yoga (the path of knowledge), Bhakti Yoga (the path of devotion), and Karma Yoga (the path of action). Each of these paths leads to self-realization and liberation, but they emphasize different aspects of the spiritual journey.

Raja Yoga, also known as Ashtanga Yoga, is a system of yoga that emphasizes the importance of meditation. The central practice of Raja Yoga is dhyana, which is a state of focused attention and concentration. Meditation allows the yogi to transcend the mind and experience the true nature of the Self.

Hatha Yoga is a system of yoga that focuses on physical postures (asanas), breath control (pranayama), and purification techniques (shatkarmas). The primary purpose of Hatha Yoga is to prepare the body and mind for meditation by improving flexibility, strength, and concentration.

Karma Yoga is the path of action in which the yogi performs actions without attachment to the fruits of their labor. The focus is on performing actions with a sense of duty and responsibility, without being motivated by personal desires or expectations. Karma Yoga teaches the yogi to transcend the ego and experience the unity of all beings.

Jnana Yoga is the path of knowledge and wisdom. The ultimate goal of Jnana Yoga is to realize the true nature of the Self (Atman) and its identity with the Absolute (Brahman). This realization leads to liberation from ignorance and the cycle of birth and rebirth.

Bhakti Yoga is the path of devotion and love. The central practice of Bhakti Yoga is the worship and surrender to a personal deity or divine being. This devotion can be expressed through various forms, such as prayer, chanting, singing, and ritualistic worship.

The eight limbs of yoga (Ashtanga Yoga) are a systematic and comprehensive approach to achieving liberation and self-realization. They include yama (moral restraints), niyama (observances), asana (physical postures), pranayama (breath control), pratyahara (withdrawal of the senses), dharana (concentration), dhyana (meditation), and samadhi (enlightenment). Each limb builds upon the previous one, leading the yogi to the ultimate goal of yoga.

The guru plays a vital role in the Yoga School as a guide and mentor on the path of yoga. The guru provides instruction on the various aspects of yoga, including meditation, breath control, and physical postures. The guru also offers guidance on how to overcome obstacles and challenges on the spiritual journey.

Samadhi is a central concept in the Yoga School and refers to a state of deep meditation and absorption in the Self. It is a state of consciousness in which the yogi transcends the mind and experiences the true nature of reality. Samadhi is the ultimate goal of yoga and leads to liberation and self-realization.

The Yoga School is considered to be one of the six major schools of Hindu philosophy. It is not considered superior or inferior to other schools, but rather complementary. The Yoga School emphasizes the importance of self-realization and liberation through physical, mental, and spiritual practices, which can be integrated with the teachings and practices of other schools of Hindu philosophy.

The Yoga School acknowledges the existence of suffering in human existence and seeks to address it through the practice of yoga. Yoga helps the yogi to understand the root causes of suffering, such as ignorance, attachment, and aversion, and provides a path to transcend these causes and achieve liberation from suffering.

Ahimsa (non-violence) is a fundamental ethical principle in the Yoga School. It is not merely a moral principle that applies only to yogis, but a universal ethical guideline that promotes compassion and respect for all living beings. Ahimsa teaches the yogi to refrain from causing harm to others, both physically and mentally, and to cultivate a sense of love and compassion towards all creatures.

The Yoga School emphasizes the interconnectedness of the individual and the universe. It teaches that the individual is not separate from or independent of the universe, but rather a part of it. The yogi seeks to realize this unity and experience the oneness of all existence.
