Reality is what you feel.
If you feel joy, splendour, peace, freedom, or strength inside, does it really matter whether it truly exists beyond that? You feel fulfilled, so what difference does it make if there is misery and poverty outside, since you do not live on the outside, but only amid your own feelings? It is simple and obvious: the inner world comes first, but people always look to the outer world for a reason to live, failing to realize that they cannot live the outer world! We can only see it, observe it, draw it, and so forth.
To be able to live it, we must at least possess the corresponding element within ourselves. If you have no sense of aesthetic, you will remain impassive and cold even when you stand before the splendours of nature, and if you feel nothing, it is as if you had nothing.
