And finally stands this, His [‘Abdu’l-Baha’s] illuminating
explanation, setting forth conclusively the true relationship between the
Revelation of Bahá'u'lláh and that of the Báb: "The Revelation of the Báb
may be likened to the sun, its station corresponding to the first sign of the
Zodiac -- the sign Aries -- which the sun enters at the vernal equinox. The
station of Bahá'u'lláh's Revelation, on the other hand, is represented by the
sign Leo, the sun's mid-summer and highest station. By this is meant that this
holy Dispensation is illumined with the light of the Sun of Truth shining from
its most exalted station, and in the plenitude of its resplendency, its heat
and glory."
