Origin of Zen in India.
Today, Zen as a living faith can be found in its pure form only among the Japanese Buddhists. You cannot find it in the so-called Gospel of Buddha anymore than you can find Unitarianism in the Pentateuch, nor can you find it in China and India any more than you can find life in fossils of bygone ages.

The first results of Yoga they call lightness, healthiness, steadiness, a good complexion, an easy pronunciation, a sweet odour, and slight excretions." (Çvet. Upanisad, ii. 8-13).
"When the five instruments of knowledge stand still together with the mind, and when the intellect does not move, that is called the highest state."
