Let's start from the morning. In the morning, when you get up, give only 5 minutes to yourself. After getting up, sit calmly on your bed and close your eyes and remember the God and anything that you want to remember but good things. Breathing is very closely relative to meditation. When you sit on, and close your eyes, take long breathing. It menas-- pull oxygen into your body slowly as much as you can. Then keep it into your body for sometime as long as you can. Then breathe out the air of your body slowly. Do this process continuously how often you can, minimum 5 times. Then leave your bed and do your usual works. A great peace you will feel in your mind. Because, there is a great role of breating in activities of mind. You will sure feel calm.
