In the past, yoga has set a strong focus on connection to a single dimension of being. The pursuit of enlightenment via practice is the core similarity between yoga and Buddhism. This realisation or enlightenment is known as Nirvana in Buddhism. Although yoga has a long history, Patanjali, a guru, first described the physical aspects of yogic practices between 400 and 500 CE. Yogic practices can be perceived as the persistence of connective tissue inside the body.
