He [VálmÃki] is said to have lived a solitary life in the woods: he is called both a muni and a rishi. The former word properly signifies an anchorite or hermit; the latter has reference chiefly to wisdom. The two words are frequently used promiscuously, and may both be rendered by the Latin in its earliest meaning of seer: VálmÃki was both poet and seer, as he is said to have sung the exploits of Ráma by the aid of divining insight rather than of knowledge naturally acquired.
