I understand that not everyone is able to spend an hour each day meditating (although if you did, you would transform your health and your life!) but there is no excuse not to make a 10-minute per day commitment to breathing practice.
Breathing is one of these clever biological processes our body is programmed to do automatically, even when we are not aware of it. In fact, it is one of the primary functions of the body is to supply our cells with oxygen. It has to be automated (subconscious) because we would be in a lot of trouble if we had to think about it all the time. But we can also control our breathing if we choose to, and when we do it in the right way, we can influence our emotions, and of course our immune system and therefore our physical well-being.
I have many fantastic mind-transforming modalities at my disposal that I use for myself and working with clients but I always teach my clients...
