I remember a prayer, which you wrote, has been asked by a certain friend to be read daily. I believe sometimes the friends through their zeal and ardour do things that are not asked in the Cause. We have only one prayer that we have to say daily. No one in the world has the power, given to him by Bahá’u’lláh to add another to that daily prayer. If we should admit this the life of the friends will soon be spent in mere prayer, which is not the aim of the Cause. The healing prayer and such ones are only for occasional use when the need arises.
