Ya Baha'u'l-Abha

Yá Bahá‘u’l-Abhá!
In this cry, all the cries of the universe are sounded, and the chord of Divine Reality is struck. The shout, “Yá Bahá‘u’l-Abhá” in this, the Day of its birth, is of more profit to thee than all the knowledge of science and all the wealth of the earth. It is the rhythm of progress, the chord of creation, the melody of eternity, and the password to the Kingdom of God. Therefore, use it to establish thyself in the realm of Divine Trust. Speak it in thy solitude, cry it in thy joy, murmur it in thy grief, and chant it in thy weakest moments—and it will give thee strength.
It is the cry that will bring the Supreme Concourse to the door of thy life, and which stations the loving trust of Abhá about thy soul. It opens the heavenly mysteries, manifests the colours, and solves the riddles of life. It absorbs all, encircles all, includes all.
To cry that phrase “O Thou Glory of the Most Glorious” is to sing in harmony with the Supreme Concourse, and to harmonize thyself with the holy “I Am” in His Court of divine omnipotent truth. It holds all there is of form, of spirit, and of the world of creative thought.
This, the Most Great Name, carries the highest vibrations, which make manifest the wisdom of the spiritual worlds. This utterance produces a spiritual result beyond all idle fancies and vain imaginations.
Yá Bahá‘u’l-Abhá!
