1. Sit comfortably on a chair or Sukhasana. Keep your hands in your lap. Close your eyes.
2. Breath slowly and gradually. Imagine you are relaxing in front of an ocean.
3. Imagine you are releasing all of your body’s discomfort to the ocean as you exhale to the imaginary ocean. (2 minutes).
4. Continue the slow breathing and release all your negative feelings and disturbing thoughts to the imaginary ocean while exhaling (2 minutes). 
5. Relax and enjoy the inner peace and calmness for as long as you would like.

This is a very good technique for slowing down your heart and breathing rates and helps to normalize your blood pressure.
