Yoga

Yoga is a group of ancient spiritual practices originating in India. As a general term in Hinduism it has been defined as referring to "technologies or disciplines of asceticism and meditation which are thought to lead to spiritual experience and profound understanding or insight into the nature of existence." Yoga is also intimately connected to the religious beliefs and practices of the other Indian religions.

Outside India, Yoga is mostly associated with the practice of asanas (postures) of Hatha Yoga or as a form of exercise, although it has influenced the entire Indian religions family and other spiritual practices throughout the world.

Hindu texts discussing different aspects of yoga include the Upanishads, the Bhagavad Gita, the Yoga Sutras of Patanjali, the Hatha Yoga Pradipika, the Shiva Samhita, and many others.^[3][4]

Major branches of Yoga include: Hatha Yoga, Karma Yoga, Jnana Yoga, Bhakti Yoga, and Raja Yoga. Raja Yoga, known simply as Yoga in the context of Hindu philosophy, is one of the six orthodox (āstika) schools of thought, established by the Yoga Sutras of Patanjali.

Goal of Yoga

here are numerous opinions on what the goal of Yoga may be, although generally they involve some kind of union, either of a personal or a non-personal nature.

Within the monist schools of Advaita Vedanta and Shaivism this perfection takes the form of Moksha, which is a liberation from all worldly suffering and the cycle of birth and death (Samsara) at which point there is a cessation of thought and an experience of blissful union with the Supreme Brahman. For the dualistic bhakti schools of Vaishnavism, bhakti itself is the ultimate goal of the yoga process, wherein perfection culminates in an eternal relationship with Vishnu or one of his associated avatars such as Krishna or Rama.
