The burning sensation you feel in your soul is the grace of God burning away your earthly desires.
Let your passions die. Die to the world. Do this by being still.
If you resist, then it clings to you. If you allow it, then you cling to it. If you are still, then it will pass you by.
To be still is the passionless passion. It is the middle way. It is that narrow path to God.
