Tejo Bindu Upanishad – Pancha Dasanga Yoga - Samadhi
The yogi should practice the fifteen limbs of yoga until there will be the manifestation of Brahman on its own accord through inference. Having reached that state, the enlightened yogi will be free from all means employed. He becomes a Raja Yogi whose radiance is beyond the range of mind and speech. It is the state that could not be explained by words or understandable. It can only be realised by the experience.
