...concerning the three daily obligatory prayers. The friends are free to choose any one of these three prayers, but have to follow the instructions revealed by Baha’u’llah concerning them. The long prayer should be recited once in every 24 hours, and is accompanied by certain physical acts. The short prayer, consisting of one verse, should be recited once a day at noon; while the medium prayer should be said three times a day: in the morning, at noon and in the evening. The believer is entirely free to choose any one of these three prayers for daily use.

While praying it would be better to turn one’s thoughts to the Manifestation as He continues, in the other world, to be our means of contact with the Almighty. We can, however, pray directly to God Himself.
