Sometimes I’m a little bit manic with different ideas flooding my mind. Although you might think of your mental state as being uncontrollable. To a great degree, mental state is related to breathing. And breathing is to some degree under conscious control.
Pranayama is the the form of yoga that focuses on breath control. Prana is the Sanskrit word for breath or life force. Ayama is the Sanskirt word for extend. Through breath control one can learn to slow down the breathing and calm the mind.
I usually start my meditation practice by concentrating on slowing down my breathing. Breathing in for a 10 count and out for a 10 count. You can focus on drawing the air in through one nostril and expelling it through the other.
You can then try a different breathing patterns. Breath of fire is a pattern of short breaths.
As I concentrate, I try to concentrate my awareness on my smell and the sounds around me. Sometimes I try to concentrate all my awareness on a part of my body say the little finger.
after a half-hour of meditation I’m much more productive. Instead of trying to do 10 things and accomplishing none, I can focus on completing one thing at a time until I’ve completed all 10.
