As the Upanishadic saying states, "Ekoham bahusyam" (I am one, let me be many) it should not be translated as - he works in different capacities though he is alone. But a worker must multiply himself as one lamp lights others; he must make others active participants in the work. It is not a matter of pride that when the worker is away, the activities close down. Somebody may feel puffed-up at the thought, 'I was the prime mover in the centre, the centre worked as long as I was there and it has come to a standstill when I have left.' But this is the certificate of the inefficiency of the worker. He must prepare a band of workers so that in his absence the work shall not halt or close down, but continue with vigour as before. He must keep a stamp of his work on the place.
The fish, in the parable of "Manu and the fish" used to occupy the whole space whenever it was kept in a pot, in a vessel, in a ditch, in a tank, in a lake, in a river etc. So the entire atmosphere must be enveloped by the worker. His test will be that within the shortest possible time, he has been able to bring together the maximum number of workers to co-operate and share in the work.
