Take one Paraliminal, consider your listening purpose. Hit play and close your eyes and enjoy the listening session.
Next day consider your purpose, review you previous day, consider your plan for the day. Does the same Paraliminal appeal? Have you done as much as you can. Does it a-line with your plans for the day? Do you have a new listening purpose?
If unsure take the next Paraliminal, consider your goal, hit play close eyes and enjoy the session. Take another Paraliminal the next day.
As always follow your gut or intuition. You cannot listen to the wrong Paraliminal, just consider your listening purpose before you start.
