Ellen Barry's interview with Yogi Nagendra in which Nagendra talks about meditation yoga and how it is practiced in India. Nagendra has known prime minister Modi since 1984 and has provided 4 yoga meetings to Mr. Modi and his ministers in Gujarat when he was Chief Minister of the state, till today as prime minister. This Yoga concentrates on meditation and tries to calm the mind as described in the Kena Upanishad (the classics of the Indian philosophy of Vedanta which form the basis of Yoga).
"The eye does not go there, nor speech, nor the mind. It is different from what is known, and what is unknown."
It is through constant and repeated practice that this meditation yoga can through concentration and yearning help one to reach a level of calmness that is a form of samadhi. Samadhi produces a level of calm and serenity mostly unknown to man.
