Bahá’u’lláh says there is a sign (from God) in every phenomenon: the sign of the intellect is contemplation and the sign of contemplation is silence, because it is impossible for a man to do two things at one time—he cannot both speak and meditate.
It is an axiomatic fact that while you meditate you are speaking with your own spirit. In that state of mind you put certain questions to your spirit and the spirit answers: the light breaks forth and the reality is revealed.
In March this year Susan Cain was recorded giving a TED talk on the theme of her book Quiet. She is well aware of the irony of pacing a platform in front of so many people and talking about introversion. I reckon she pulls the feat off amazingly well. What do you reckon? Particularly moving are the memories of her grandfather she shares towards the end of her talk and also her teasing out the implications of silence for spirituality and creativity.
