All wisdom traditions, religious and secular, speak of the ability to maintain a still place within, no matter how busy we are. The word mindfulness traces its origin to the pali word “to remember”

The true saint goes in and out amongst the people

and eats and sleeps with them

and buys and sells in the market

and marries and takes part in social intercourse,

and never forgets God for a single moment.

Abu Sa’id ibn Abi l-Tkayr, Sufi Poet, 967 – 1049
