Question : So one should not try to perpetuate blissful or ecstatic states?
Ramana Maharshi :The final obstacle in meditation is ecstasy; you feel great bliss and happiness and want to stay in that ecstasy. Do not yield to it but pass on to the next stage which is great calm. The calm is higher than ecstasy and it merges into samadhi. Successful samadhi causes a waking sleep state to supervene. In that state you know that you are always consciousness, for consciousness is your nature. Actually, one is always in samadhi but one does not know it. To know it all one has to do is to remove the obstacles.
