Relative energy 2

The knowledge about how the brain works is increasing fast these years. Research is intense. New drugs are developed.
Old drugs as tobacco, coffee and tea shows that many individuals would like to increase the energy and capacity of the brain. It is no wonder, as the world we live in is extremely complex, even compared to the extreme complexity of the brain.
We can increase the efficiency of our brain by study and thinking, as we know. Living in a stimulating environment, be it a university or a creative work place, will boost the capacity of the mind.
But we can also train the brain, as we can train the body. There are many methods, including physical exercises, food, sound and meditation. One very essential and basic matter is breathing.
If we can not breath at all, the alarm systems in our organism are activated. This is very good, as it helps us to survive as physical entities.
But if our breathing is good enough to give the physical body energy, but not good enough to support the brain, there is no alarm. On the contrary, the brain is slowed down and if feels as the situation is all right, but a bit passive.
In order to support the brain with energy, it is recommended (by Tarthang Tulku in Kum Nye Relaxation) that we breath with slightly open mouth. Then we will get energy not only to the physical processes in the body, but also for the brain.
