According to the author Patanjali, samadhi is the last of the eight elements of yoga practice. It is described as a state in which the mind is only conscious of the object of concentration. It makes the practitioner unaware of the outside world, so much so that they will not respond to stimulus and sometimes may almost appear dead. It is popularly believed that deceased yogis are not actually dead, but rather are rapt in deep meditation. That is why the burial places for deceased ascetics are usually referred to as samadhi shrines.
Samadhi shrines in India are often visited and kept clean by the devotees. Hindu rituals, meditation, prayer and mantra chanting may take place in samadhi shrines. Some samadhi shrines have become places of pilgrimage for people seeking the ascetic´s continued blessing.
