I got this one from the book Amazing secrets of New Avatar Power by Geof Gray-Cobb. You simply take your first name and the initial letter of your last name and create a chant. Get into a comfortable position, close your eyes and start counting down like this (I am gonna make up a name Tiffany Woods as example):

Ten, relax Tiffany W... Nine, relax Tiffany W... Eight, relax Tiffany W... Seven, relax Tiffany W... and so on until you reach one.

Feel your muscles relax as you count down. You can do this as often as you want and anytime, anywhere you want. You'll feel your hands beginning to tingle, that's a sign that energy is flowing freely and your vibration is getting higher.

I'll add one method:)

Outside the muscle tension, we can also try pressurize and then release. This actually makes me aware of the tension inside the head. There's also a time when I released too much that the heartbeat becomes much slower during medical exam, and the doctor recommended me to be hospitalized:I

Your techniques are really interesting , I will try
