At the time when thou art working . . . thou must be controlled by the attraction of the love of thy Glorious Lord and mindful of mentioning His splendid Name.

‘Abdu’l-Bahá, Bahá’í World Faith, p. 377

Consider the motive of every soul, and ponder the thought he cherisheth. Be ye straightway mindful and on your guard.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 315

He [Mashhadi Fattah] was always in a certain corner of the prison, silently meditating, occupied with the remembrance of God; at all times spiritually alert and mindful, in a state of supplication.

devoted their days to all that is best in human life: they had seeing eyes; they were mindful and aware; they had hearing ears, and were fair of speech. Their sole desire was to please Bahá’u’lláh. To them, nothing was a bounty at all, except service at His Holy Threshold.

‘Abdu’l-Bahá, Memorials of the Faithful, p. 40-41

Two calls to success and prosperity are being raised from the heights of the happiness of mankind, awakening the slumbering, granting sight to the blind, causing the heedless to become mindful, bestowing hearing upon the deaf, unloosing the tongue of the mute and resuscitating the dead. The one is the call of civilization, of the progress of the material world . . . The other is the soul-stirring call of God.
