"Not thus, Ananda, is the Tathāgata respected, venerated, esteemed, worshipped and honoured in the highest degree.

"There are two kinds of worship: in a material way (āmisa-pūjā) and through (practice of) the Dhamma (dhamma-pūjā). The worship through (practice of) the Dhamma is the better of the two" (A. II).
