Paul Brunton said this quote

“ As his mind becomes purer and his emotions come under control, his thoughts become clearer and his instincts truer. As he learns to live more and more in harmony with his higher Self, his body's natural intuition becomes active of itself. The result is that false desires and unnatural instincts which have been imposed upon it by others or by himself will become weaker and weaker and fall away entirely in time. This may happen without any attempt to undergo an elaborate system of self-discipline on his part: yet it will affect his way of living, his diet, his habits. False cravings like the craving for smoking tobacco will vanish of their own accord; false appetites like the appetite for alcoholic liquor or flesh food will likewise vanish; but the more deep-seated the desire, the longer it will take to uproot it--except in the case of some who will hear and answer a heroic call for an abrupt change. ”
