`Abdu'l-Bahá teaches how the practice of invocation or repetition of “The Greatest Name” (Alláh-u-Abhá, God is Most Glorious) leads to union with God, illumination and spiritual rebirth. The use of invocation is well developed among the mystics of Islam, the Sufis. The repetition of sacred phrases is called dhikr (promounced zikr, meaning remembrance). This spiritual practice of invocation is praised by `Abdu'l-Bahá. He encourages spiritual seekers to “recite the Greatest Name at every morn, and (to) turn…unto the kingdom of Abhá, until though mayest apprehend the mysteries.
