In order to know, is to know of not knowing, therefore to know is an endless journey of understanding. One is only ignorant to believe otherwise.....the only true knowledge is that of within, only one can understand ones self. Why we choose to never reflect on ourselves in society and only scrutinize others is beyond me. We live in a society of all knowledge yet none of understanding.
So, in the art of knowing yourself, yes, you can know yourself only if you understand that knowing all of yourself, is an impossibility for the facts of life yet have been revealed completely. Only one can choose to how much they want to understand, they may have knowledge of themselves, but to of understanding all is something of false reality.
Life is only what you choose to experience; When foul experiences and sought knowledge are more important than those of good intentions to be that of primary focus by almost all; How much longer will these good intentions last before disappearing in the memory of time.
