 There's also a color to associate with this, which is white. So what I'd like you to do is imagine white energy going into your lungs, and then while you're doing the exhalation, just imagine that white energy turning into brown energy and then coming out of your mouth and just shooting out and then back into the ground so it disintegrates. So just imagine white energy, breathe in, fill your lungs with that white energy and then breathe out with the sound. Place your tongue just behind your teeth as you make the sound. Look up. And then like that, bad energy, the negative energy or the waste come out and just go back into the ground.
