The goals of yoga are varied and range from improving health to achieving Moksha. Within Jainism and the monist schools of Advaita Vedanta and Shaivism, the goal of yoga takes the form of Moksha, which is liberation from all worldly suffering and the cycle of birth and death (Samsara), at which point there is a realisation of identity with the Supreme Brahman. In the Mahabharata, the goal of yoga is variously described as entering the world of Brahma, as Brahman, or as perceiving the Brahman or Atman that pervades all things.For the bhakti schools of Vaishnavism, bhakti or service to Svayam bhagavan itself may be the ultimate goal of the yoga process, where the goal is to enjoy an eternal relationship with Vishnu.
