Guatama Buddha said this quote

A wise person can enter and dwell in his own teacher's knowledge, having realized it for himself through knowledge.

~ Guatama Buddha

When we free ourselves from desire, we will know serenity and freedom.

~ Guatama Buddha

Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.

~ Guatama Buddha
