The ‘Master Key’ to self-mastery is self- forgetting. The road to the palace of life is through the path of renunciation.
(‘Abdu’l-Bahá: Star of the West, Vol. XVII, p. 348)
This is the Day when every ear must needs be attentive to His voice. Hearken ye to the Call of this wronged One, and magnify ye the name of the one true God, and adorn yourselves with the ornament of His remembrance, and illumine your hearts with the light of His love. This is the key that unlocketh the hearts of men, the burnish that shall cleanse the souls of all beings.
(Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 203)
