Meditation on the breath is a basic meditation, you can't go wrong with it. Or at least, I hope not!
Moving on, the breathing meditation is a basic meditation. It focuses on meditating on your breathing. This is the first meditation I ever tried, and I go back to it when I need to really concentrate.
First sit into a cross legged position. Second take a moment to ground yourself, imagine your rooted to the ground, I always say! After start closing your eyes, and breath. Try just counting the number of seconds until your breath.
Sometimes your walk, it's a breathing meditation but also, a movement meditation. (Active meditation, by the way). You walk down a block that is quite. You focus your steps to match your breath.
Either or, this is one of the easiest meditations that require no skill, so good luck.
