(dc - fast day 6) from kat

"Happy are those who spend their days in gaining knowledge, in
discovering the secrets of nature, and in penetrating the subtleties of pure
truth! Woe to those who are contented with ignorance, whose hearts are
gladdened by thoughtless imitation, who have fallen into the lowest depths of ignorance and foolishness, and who have wasted their lives!"

- Abdu'l-Baha, Some Answered Questions, p. 136
