In yoga the term is used to indicate some kind of trance and there are various kinds of samadhi. But the samadhi I speak to you about is different. It is sahaja samadhi. In this state you remain calm and composed during activity. You realise that you are moved by the deeper self within and are unaffected by what you do or say or think. You have no worries, anxieties or cares, for you realise that there is nothing that belongs to you as ego and that everything is being done by something with which you are in conscious union.
Ramana Maharshi (1879-1950)
