If something requires your attention, the answer is no.
Walking or yoga are fine since they are both meditative activities anyway, but avoid any activity that causes your brain to stay in the Beta state - don’t work, use the computer, talk or read. Your brain will not entrain to the desired frequency if it’s busy.
Please DO NOT drive or operate machinery while you are using the program.
Some of the bonus tracks are meant to be listened to while working, studying, creating or relaxing; but save the main tracks for a dedicated meditation practice where your brain is allowed to relax into the program without constantly being pulled away.
This way you’ll reap the greatest benefits in the shortest amount of time possible!
