समुझत सरिस नाम अरु नामी।
प्रीति परसपर प्रभु अनुगामी।।
The name and the object named though similar in significance are allied as master and servant, one to the other. (That is to say, even though there is complete identity between God and His name, the former closely follows the latter even as a servant follows his master. The Lord appears in person at the very mention of His Name).
