From The Book of Joy: Lasting Happiness in a Changing World:
by the Dalai Lama:
A scientifically controlled study conducted by German researchers at the University of Kassel has shown that while the chest area of an average person emits only 20 photons of light per second, someone who meditates on their heart center and sends love and light to others emits an amazing 100,000 photons per second. That is 5,000 times more than the average human being.
Numerous studies have also shown that when these photons are infused with a loving and healing intent, their frequency and vibration increases to the point where they can literally change matter, heal disease, and transform negative events.
Ten minutes of meditating on compassion, on kindness for others, and you will see its effects all day. That’s the way to maintain a calm and joyous mind.
