Breathing can be done through your mouth or your nose
Mouth vs. nose breathing shows you whether you tend to engage and relate more with your external world or your internal world.

Mouth breathing
Breathing through your mouth shows that you are physically and emotionally engaged with your life.

Whenever you laugh or cry or run or exercise or sigh or yawn, you breathe through your mouth, so Natural Breathing is naturally done through the mouth.

Mouth breathing is also preferred in Natural Breathing because it is easier and gives you faster access to a full breath and more air than through the nose.

Nose breathing
Breathing through your nose connects you with your internal world.

Nose breathing pacifies you. This may be good to do if you want to meditate or calm down.

Sometimes nose breathing can take place at the end of a session, but is not ideal, since it dis-engages physical and emotional awareness.

Alternating Mouth and Nose breathing
Breathing in through the nose and exhaling through the mouth or any combination thereof can only be done by mentally controlling your Life-force. It takes effort and a certain level of muscle engagement to constantly change the flow of the air, and thus uses up Life-force, keeping you below the Breathing Threshold.

Unobstructed Natural Breathing is always done through the mouth.

Chest vs. Belly breathing shows you whether you engage personally or are a disengaged observer.

Chest breathing shows that you are interested in your life, engage in it, take charge, and take your life personally.

Belly breathing shows that you stuff your feelings, is a spectator and don’t face your circumstances. You engage mentally and physically, but no awareness of your actual personal Life-Journey.

Natural Breathing starts with your chest
Your inhale should be filled up from the top of your chest and then expand, down through your solar plexus, into your abdomen, and then to the rest of your body. If your breath jumps over and avoids your solar plexus area, you are missing your personal power to create the life that you want.

If a person intends to do Natural Breathing, but is educated in diaphragmatic breathing, which has a different purpose than Natural Breathing, the person needs to be re-educated on how to breathe into their chest.

Your Breathing Threshold is the point in your breathing where you have an opportunity to retain more energy than you use up.

Your Breathing Threshold is the point in your breathing, where your inhale tends to end, and your exhale starts. It is the depth you are inclined to inhale to.

When you do the 5 Breathing Basics, you breathe more than you are inclined to and thus retain more Life-force than sub-ventilating suggests. This is called “Breathing Beyond your Breathing Threshold”.

• You ADD more Life-force and go beyond your Breathing Threshold by being Aware and Inhaling deeper than you are inclined to.
• You USE UP Life-force and breathe below your Breathing Threshold by being Unaware, Moving and Thinking.

Locating the Breathing Threshold
Your Breathing Threshold is encountered in every breath.

The depth of your inhale, before you hit the Breathing Threshold varies, depending on how much Life-force you are using up.

For example, if you run, you can breathe deeply, without going beyond your Breathing Threshold. If you are very present and relaxed, you don’t need to breathe much to go beyond your Breathing Threshold.

How deep and fast you need to breathe to go beyond your Breathing Threshold, depends on how much energy you use up.
