Extract from a Tablet of ‘Abdu’l‑Bahá

As regards obligatory prayer, this should be recited by each believer individually, albeit its performance is not dependent upon the availability of a private place. In other words, obligatory prayer may be performed alike at home or in the Temple, which latter is a public place, but on condition that each believer recite it individually. As for devotions other than obligatory prayer, if these be chanted jointly and with a pleasant and affecting melody, this would be most acceptable.
