O servant of Baha!

O servant of Baha! It behoveth thee to render thanks unto the Threshold of the Lord of Oneness for the afflictions that have befallen thee, inasmuch as the adversities that are borne in the path of the one true God are but the revelations of His tender mercy, and any such tribulation is the essence of His bounty.
 This life is like unto vapour in a desert and the existence of every thing is as a mere illusion, evanescent and bound to extinction. That which endureth is the spiritual reality, it is the shining essence; it is life eternal, it is undisturbed felicity, unfading and perpetual, flourishing and plenteous. The revolution of cycles is powerless to ravage it, nor can the succession of ages and centuries molest it. Therefore, this divinely-ordained reality, this heavenly sign, must needs be preserved.
 And the amazing thing is this that the most effective means whereby this light of truth is safeguarded and protected is the onslaught of the enemies, grievous ordeals and manifold hardships. The globe of this lamp is the tempestuous winds and the safety of this ship lieth in the violence of tumultuous waves.
 Therefore one must show forth gratitude in the face of Job-like afflictions and must evince joy and pleasure at the unyielding cruelty of evil-doers, inasmuch as such tribulations lead to immortality, and serve as the supreme factor to attract His consummate blessings and infinite bestowals. And upon thee be the glory of the Most Glorious.
