I read and tried a way to help us meditate and clear our mind faster. Try squatting in a quiet room where the only sound that you can here is your breathing. Try focusing on your breathing so to take your mind off of everything else. Another way is to have a dripper and a bowl 2 to 3 ft away under it. Listen to the sound as it hits the water surface. Once you've mastered focusing your mind on those sounds, you can easily focus and rid your mind of any unnecessary thoughts.
