You should respect each other and refrain from disputes; you should not, like water and oil, repel each other, but should, like milk and water, mingle together.
A wrong action may not bring its reaction at once, even as fresh milk turns not sour at once: like a smouldering fire concealed under ashes it consumes the wrongdoer, the fool.
Do not believe anything because it is said by an authority, or if it is said to come from angels, or from Gods, or from an inspired source. Believe it only if you have explored it in your own heart and mind and body and found it to be true. Work out your own path, through diligence.
All the holy words you read and all the holy words you speak are as nothing if you do not act upon them. Even if you read little and say little but live the right way, forsaking craving, hatred and delusion, you will know the truth and find calmness and will show others the path.
