Ramana used the example of employing a thorn to pluck out another, after which you would discard both, since they had served their purpose.


A Course In Miracles puts it this way:

"It cannot be emphasized too often that correcting perceptions is merely a temporary expedient. It is necessary only because misperception is a block to knowledge, while accurate perception is a stepping stone towards it. The whole value of right perception lies in the inevitable realization that all perception is unnecessary. This removes the block entirely. You may ask how this is possible as long as you appear to be living in this world. That is a reasonable question. You must be careful, however, that you really understand it. Who is the 'you' who are living in this world? Spirit is immortal, and immortality is a constant state. ...it is not understood by being compared to an opposite. Knowledge never involves comparisons."

"Go to the root of both."
