This is easy to use. It is a breath meditation lasting as long as one breath in and one breath out. There's meditation/awareness in every breath. But it's easy to forget to breath when you're stressed, isn't it?
Please sit comfortably or lie down. Allow your shoulders to relax. Relax you neck.
Take a deep breath, s-l-o-w-l-y in through your nostrils.
Feel the air coming in, your belly slowly rising.
While you hold your breath for 3seconds, close your eyes.
Now breathe out through your mouth. Exhale with relief making a sound such as Ahhh...
That felt good, didn't it? You may repeat as you wish throughout the day.
