I have a mild headache took some ibuprofen 10 minutes ago. Best thing to do is rest in stillness. "feel them out purely" well that has to do with again noise reduction so that brainwaves can allow interference patterns to click a solution. Send the problem in then all the waves bounce off it giving you your options and that is the key. You have patterns in you that might fit so bounce them off the held thought of what you are trying to find and some may stick. Definitely, the stillness allows you to try all the options if you are silent long enough.
You could also mold a solution around the problem without the search for options in memory.
