Sit comfortably and close your eyes. Imagine a fast-flowing stream of light flowing into your heart, pure, brilliant, clear, and comfortable. As it touches your heart, you experience the first budding of happiness, which grows stronger and stronger within you. You understand that in everything you do, feel, and say in your daily life, happiness will be in you, inspiring and influencing your thoughts and deeds.
— Christopher Hansard in The Tibetan Art of Positive Thinking
