The rain itself, was the inspiration for this practice, do you know why?
One day when it rains, try to stand by your window and watch carefully what the drops of water do. These come and beat against the glass, which instead of holding them back, simply lets them run down.

We should also learn to do the same thing with our mind and the thoughts that crowd it daily.
Whether positive or negative, thoughts come continuously to disturb our peace and quiet, as we have the habit of keeping them with us (especially the negative ones) for hours, if not even days!
This causes the so-called “brooding”, which often creates anxiety and distress within us.
Thanks to meditation instead, we can learn to have a “Mindful” attitude, that is awareness and observation.
Thoughts are and always will be there, as we are the ones who create them, but instead of judging them and keeping them with us, we simply learn to observe them and let them go, as glass does as raindrops.
The sound of the rain also has a calming and relaxing effect, so I recommend this meditation whenever you need to calm down or even before you go to sleep, as part of your “night routine”.
Effects of the Sound of Rain
What makes the sound of rain so beneficial for a relaxing routine is that it is considered a white sound, meaning, it occupies its entire auditory spectrum and cancels out other sounds that may be in the background.

These sounds are widely used to calm any human being, from the smallest to the largest, and it is because of their ability to cover other sounds.
There is no need to wait for a rainy day to relax or sleep better.
In fact, I’m going to leave you with a video featuring the sounds of rain.
