There are lots of different ways to meditate, and no one way is better than the other. There are guided meditations, silent meditations, mantras you can use to focus your mind, chanting meditations, chakra meditations, movement meditations, and plenty more.
I will share what I know and help you find what is right for you.
If you can begin to practice for just a minute or two every day, you can use that practice of calm when you're mad, or worried, or upset. If you learn to meditate, just for short periods, then when something happens that would normally stress you, you will be ready to just take one breath, find that place of peace, and take things as they come.
