Samadhi is the eighth and the last step of Yog. Making the body static, drawing the senses inward and stilling the mind for a longer duration and merging Chit in Atma consciousness is one part of samadhi; but to engage the body, mind, intelligence and chit in the work whole heartedly is Samadhi in a waking state. Later one is the need of the hour and efficiency in the present context of the day. He is doubly blessed. He becomes pure at heart and makes his surroundings including human hearts around, pure by his selfless actions, which are for the benefit of the society-at-large.
