Sit completely still: Drop all physical actions and settle into an upright, dignified seat. 

Drop your chin: Let your eyes close and let your face soften. 

Ask the inner question: Whisper the question inside your mind: 'Who is the one thinking these thoughts right now?' 

Do not look for an answer: Do not try to answer the question with words or logic; simply look into the empty space right after the question ends. 

Rest in the blank gap: Hold your focus steady inside that quiet, wordless gap for as long as it lasts. 

Re-ask if thoughts return: If thoughts restart, simply drop the question back into your mind to clear the screen again.
