The easiest way to relax is to stop trying to make things different. Rather than trying to create another state, simply allow space for whatever is going on. If you sit down after being busy and your mind feels agitated or chaotic, try just seeing that state for what it is and accepting it. You might frame your whole mind-body expereince with the mental note “chaos, chaos”. Instead of having an agenda to change the quality of your energy, you enjoy the use of this simple key to just open to the energy that is there. This does not mean either spacing out or being entanglesd in your agitated thoughts. Rather, through accpetance we settle back into natural awarenss of whatever is present. Then things settle down by themselves in a natural way. Struggle comes from not accepting what is present.
