One cannot change oneself, but one can realise oneself.
Hui-Neng* called Selfrealisation, the realisation of one’s own mind essence.
(*Sixth Patriarch of Chan Buddhism)
I think the modern parallel to this is : “Know Thyself”, which is good advice because only by being aware of what ‘makes you tick’ can you institute real change. By becoming aware of your strengths and weaknesses you are in a better position to judge what will work and not work for you. So I think your statement that you cannot change yourself, but can realize yourself, is very apposite and very wise. I was a tad disappointed about some of the replies you received because I think what you said is very valuable and informed. Ancient wisdom should always be respected because it has been wrought out of experience and wisdom.
What if a majority of the population doesn’t agree with your assessment of the value of “ancient wisdom”? There is plenty in ancient wisdom no one would waant imposed on him or herself, including you.
The phrase “ancient wisdom” tells us nothing. There are countless forms of “ancient wisdom”. Which form are you suggesting? Tell us specifically what you mean by it. Would it by any chance include slavery, torture and execution? Those were elements of “ancient wisdom” too. I suspect you are defning “ancient wisdom” as the elements you agree with.
