Advaita is the only system that gives us complete control over ourselves, takes off all dependence and its associated superstitions, thus making us brave to suffer, brave to do, and in the long run, attain to absolute freedom.
I still indulge in a glass of wine or chocolate - treats are mandatory. Without deviating from the day-to-day healthy diet once in a while, it wouldn't be sustainable for me, and that's what I wanted: an approach to eating to last my entire life.
Tomorrow and plans for tomorrow can have no significance at all unless you are in full contact with the reality of the present, since it is in the present and only in the present that you live. There is no other reality than present reality, so that, even if one were to live for endless ages, to live for the future would be to miss the point everlastingly.
No one step back, that is the idea.... Fight it out, whatever comes. Let the stars move from the sphere! Let the whole world stand against us!.... What of it? Thus fight! You gain nothing by becoming cowards.... Taking a step backward, you do not avoid any misfortune.
