His inner eye had already discerned on my brow the seal of God.

Bahá'u'lláh, the Great Perfection—blessed be His words—in the past, the present and forever—chose this insignificant one to be His successor, not because I was the first born, but because His inner eye had already discerned on my brow the seal of God.

Before His ascension into eternal Light the blessed Manifestation reminded me that I too—irrespective of primogeniture or age—must observe among my sons and grandsons whom God would indicate for His office. My sons passed to eternity in their tenderest years, in my line, among my relatives, only little Shoghi has the shadow of a great calling in the depths of his eyes.
