Ramana Maharshi often used the term sahaja samadhi to describe what he regarded as the best state. Although the word samadhi is too often associated with yogic trance, there is nothing of the kind in his use of this term. He said it was the best state because it was quite natural, nothing forced, artificial, or temporary. We may equate it with Zen's "This life is very life" and "Walk On!"
