- Disease in most of us is due to a waste of prana generated in the body. Complete relaxation of the body during sleep and several times during the day will conserve the prana generated in the body.
- Thoughts of happiness, hope, faith, courage and strength tend to conserve prana. While thoughts of sorrow, fear and worry tend to deplete the prana generated in the body
- Stand or sit with spine erect, point your lips just as you do when you whistle, leaving a small hole. Now close your nostrils with the fingers and inhale slowly a deep breath through the pointed mouth. Close the mouth and exhale through the nostrils. Practice this about ten times. This will cure diseases due to impure blood.
- Practise whistling each day for about five minutes. This will strengthen the lungs and purify the blood as well.
