True Alchemy or the Quest for Perfection (Izvor Collection, Volume 221)

Don't battle against your weaknesses and vices for it is they who will win: instead, learn to make them work for you. Jealousy, anger, covetousness and vanity can all be harnessed and put to work for whatever purpose you choose. Take the example of the forces of nature: electricity, the wind, waterfalls, thunderbolts... Now that man has learned to domesticate them and work with them, they have helped him to become rich. And yet, to begin with, they were hostile forces. You find it perfectly normal to use natural, physical forces so why be astonished at the idea of using your own primitive forces? Once you know the rules of spiritual alchemy you will be able to transform and use the negative forces that exist in such abundance within you.
