Yogis

To the ancient Yogis, the body was seen as a vehicle for the soul, and this is a useful metaphor in the modern context.

The mystical school of Yogis was established by Patanjali, the founder of one of the six philosophical systems of ancient India. It is supposed that the Neo-platonists of the second and third Alexandrian Schools were the followers of Indian Yogis, more especially was their theurgy brought from India by Pythagoras, according to the tradition.

Bagchi and Wenger (1957) also found the normal alpha pattern, sometimes with good amplitude modulation, in the EEG records of some Yogis during meditation.
