I have a question regarding buddhist custom of chanting this phrase:
Araham samma-sambuddho bhagava
Buddham bhagavantam abhivademi.
Svakkhato bhagavata dhammo
Supatipanno bhagavato savakasangho
Should this phrase be chanted only by a monk/nun after dhamma talk, or can a group of lay people join and sing/chant along together with the monk/nun?
