I beg of Him, through His unfailing aid, to cause this return of thine to exert a powerful effect. Such a thing can only come about if thou dost divest thyself of all attachment to this world, and dost put on the vesture of holiness; if thou dost limit all thy thoughts and all thy words to the remembrance of God and His praise; to spreading His sweet savours abroad, and performing righteous acts; and if thou dost devote thyself to awakening the heedless and restoring sight to the blind, hearing to the deaf, speech to the mute, and through the power of the spirit, giving life to the dead.
(‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 172-173)
The performance of baptismal celebration would cleanse the body, but the spirit hath no share; but the divine teachings and the exhortations of the Beauty of Bahá will baptize the soul. This is the real baptism. I hope that thou wilt receive this baptism.
(‘Abdu’l-Bahá, Bahá’í World Faith, p. 390)
