It is the Divine Grace which makes you progress, and with the Divine Grace feel the Divine Joy. But instead of identifying yourself with the Grace which makes you progress, you identify yourself with the ugly thing you want to get rid of; and so, naturally, you feel like it and suffer.
That is an experiment you can make if you are just a little conscious. There is something in you which you do not want, something bad – for one reason or another you do not want it, you want to pull it out well, if you identify yourself ever so little with that thing, you feel the pain of the extraction; if on the contrary, you identify yourself with the Divine Force which comes to liberate you, you feel the joy of the Divine Grace – and you experience the deep delight of the progress you have made.
And this is a sure sign for you, a sure indication of what you identify yourself with. If you are identified with the forces from below, you suffer; if you are identified with the forces from above, you are happy.
