The fifth spirit is the Holy Spirit. This Holy Spirit is the mediator between God and His creatures. It is like a mirror facing the sun. As the pure mirror receives light from the sun and transmits this bounty to others, so the Holy Spirit is the mediator of the Holy Light from the Sun of Reality, which it gives to the sanctified realities. It is adorned with all the divine perfections. Every time it appears, the world is renewed, and a new cycle is founded. The body of the world of humanity puts on a new garment. It can be compared to the spring; whenever it comes, the world passes from one condition to another. Through the advent of the season of spring the black earth and the fields and wildernesses will become verdant and blooming, and all sorts of flowers and sweet-scented herbs will grow; the trees will have new life, and new fruits will appear, and a new cycle is founded. The appearance of the Holy Spirit is like this. Whenever it appears, it renews the world of humanity and gives a new spirit to the human realities: it arrays the world of existence in a praiseworthy garment, dispels the darkness of ignorance, and causes the radiation of the light of perfections. Christ with this power has renewed this cycle; the heavenly spring with the utmost freshness and sweetness spread its tent in the world of humanity, and the life-giving breeze perfumed the nostrils of the enlightened ones.
In the same way, the appearance of Bahá’u’lláh was like a new springtime which appeared with holy breezes, with the hosts of everlasting life, and with heavenly power. It established the Throne of the Divine Kingdom in the center of the world and, by the power of the Holy Spirit, revived souls and established a new cycle.
