Spend some time meditating. Doesn’t matter what meditation practice you start with, really. (You may develop preferences later, but for right at the beginning, just try one. And if you’re overwhelmed with options, I’d recommend starting with a noting practice. Just watch what arises in your awareness without judging, holding onto it, or pushing it away. “Itch”, “thought”, “emotion”, “breathing”, “mental image”, etc. If multiple things are in your awareness, just pick one. Set a timer when you start and do the meditation practice until it goes off. Start with 10 minute sessions. (If that’s too much, try 5 minutes.) Also, it can be done in any relatively comfortable bodily position.
