Where knowledge ends, religion begins. - B. Disraelihttp://www.buddha-vacana.org
As a sweet-smelling and beautiful lotus flower may grow upon a heap of rubbish thrown on the highway, so also, out of the rubbish heap of beings may appear a disciple of the Buddha, who with his wisdom, shines resplendent in wisdom. -/ Dhp 58-59
