Yes, you got it correct. Start above the belly button, go down to the left side of the body then down to below the belly button then up to the right side of the body then back to above the belly button. If you are in front of a person doing this is and looking at them it will appear clockwise but if you’re behind a person and can magically see through their body it will appear counter-clockwise. By rubbing clockwise you are in harmony with the natural flow of energy in that region. Rubbing counter-clockwise disrupts the harmony.
I should also point out that it is best to use your out-hand rather than your in-hand. In humans energy flows out of one hand and in the other. Which hand is in or out is not the same for all humans, though. Usually (but not always) the dominant hand is the out-hand, so it’s usually a safe bet to use your left hand if you’re left-handed and right hand if you’re right-handed. Once we open up our inner senses we can become acutely aware of how energy flows in our bodies and it will become obvious which hand is which.
By the way, it is also very helpful and powerful for life partners to rub each other’s donuts and for parents to rub the bellies of their babies.
