The mind and the heart are like a house in which lodgers are received.They may be honest and quiet, or, on the other hand, noisy and destructive, doing much injury to the dwelling which shelters them.
Let us beware, then, of the ideas which we receive beneath our roof; let us not collect them at random from every book or magazine [or T.V., internet, commercials, music videos, etc.] which comes across out path. There are ideas which, when received as lodgers, can only be got rid of with great difficulty.
