Ghazali has said in his Alchemy of Happiness that the spiritual path is like shooting an arrow into the dark. You cannot know where it will fall or what it will strike. You are going along blindly, not knowing what you really seek or what you have achieved so far. There is only one commendable procedure; and so if your walk along the spiritual path makes you better able to manage your thoughts, and makes you stronger on your feet, you will be able to realize all that can be accomplished by patience and by hope. If you only paid attention to this all your life long and watched what you did, you would see your own progress, and what encouragement that would be!
