Believe Only truth. Don’t believe in what you have heard; don’t believe in the traditions because they have been handed down for generations; do not believe in anything because it is rumoured and spoken by many; do not believe merely because a written statement of some old sage is produced; do not believe in conjectures; do not believe in that truth to which you have become attached by habit; do not believe merely the authority of your teachers and elders. After observation and analysis, when it agrees with reason and is conducive to the good and gain of one and all, then accept it and live up to it. Pray do not, therefore, believe me when I come to the philosophical issues until and unless you are convinced of what I say, either as a sequel to proper reasoning or by means of a practical approach. Buddha.
