Greatness is a way of being, entirely in itself, not a thing well done, no matter how well. A person could practice and practice to perform, outstandingly, then after their endeavour, struggle to tie their own shoelaces, or dull an entire room with their stupidity. Greatness, is a side-effect of soul, mutually exclusive to lower mind. Lower mind might want to be great, it might even pretend to be great, but it can never be great, no matter how hard it tries, that's why it mocks such notions. The best it can hope for, is to be cauterised and decommissioned, so that the promise of true greatness can begin to emerge, and finally flourish. Only, by that time, who wants it?
