WHY YSK- Many people practice mindfulness and meditation as part of their lives, and some would like to but feel like they don’t have time to sit down and meditate properly. Once you’ve gotten used to doing it as a part of your daily activities, it becomes easy to simply take a few breaths and gain some peace from your everyday existence. You don’t need to wait for a time when you can sit and clear your mind completely. It’s a nice bonus, but not necessary for living a mindful life.
That’s calming down yourself for bed which is very different. Meditation is building mindfulness. Going to sleep is the opposite of mindfulness. If your goal is to meditate, then this doesn’t help.
