Can you give me a short summary of Mindfulness and how to practice it?
Mindfulness is a technique that can be used to bring your mind and focus into the present moment, and calm your nervous system.

The most common way to begin to practice mindfulness is to narrow and focus your attention on your breath. Some techniques prefer breathing in through the nose and out through the mouth, although this is not required. One way to narrow your attention is to closely observe the sensation of cool air as it passes over the tip of your nose, and the sensation of your chest falling as you exhale. Allow any rising thoughts to pass through your mind without paying attention to them, or engaging with them.

Other techniques involve focusing your attention to sensations in your body like hot and cold, or pain. You can also bring your focus to feelings like fear, anxiety, or love - focus your attention on where exactly in the body you feel those feelings. You can also move your attention to external stimulus like sounds, and your visual field.

Mindfulness is an extremely powerful technique that anyone can do from anywhere. Good luck practicing!
