do not believe a thing simply because it has been said.
do not put your faith in traditions only because they have been honoured for many generations.
do not believe a thing because the general opinion believes it to be true or because it has been said repeatedly.
do not believe a thing because the probabilities are in its favour, or because you are in the habit of beliveing it to be true.
do not believe in that which comes to your imagination, thinking that it must be the revelation of a superior being.
believe nothing that binds you to the sole authority of your masters or priests.
that what you have tried yourself, which you have experienced, which you have recognised as true, and which will be beneficial to you and to others; believe that, and shape your conduct to it.
