Funny how things work. Those that are fluent in just about any discipline do it without “force”.
You can be a chef and intuitively understand that special ingredient to get that “just right” flavor. You can go to school and learn about cooking but the skills that transcend forced conscious thought must be learned like an art form.
Software development follows a similar pattern. Sometimes when you have a bug in a program you can jump to the right place without knowing why … and there it is just “leaping” off of your monitor in full view for anybody who knew where to look.
Sleep probably follows this same pattern as in many Zen teachings … “Seek and you will not find”.
