These verses draw hearts that are pure

They who recite the verses of the All-Merciful in the most melodious of tones will perceive in them that with which the sovereignty of earth and heaven can never be compared. From them they will inhale the divine fragrance of My worlds — worlds which today none can discern save those who have been endowed with vision through this sublime, this beauteous Revelation. Say: These verses draw hearts that are pure unto those spiritual worlds that can neither be expressed in words nor intimated by allusion. Blessed be those who hearken.

Assist ye, O My people, My chosen servants who have arisen to make mention of Me among My creatures and to exalt My Word throughout My realm. These, truly, are the stars of the heaven of My loving providence and the lamps of My guidance unto all mankind. But he whose words conflict with that which hath been sent down in My Holy Tablets is not of Me. Beware lest ye follow any impious pretender. These Tablets are embellished with the seal of Him Who causeth the dawn to appear, Who lifteth up His voice between the heavens and the earth. Lay hold on this Sure Handle and on the Cord of My mighty and unassailable Cause.

Adorn your heads with the garlands of trustworthiness and fidelity, your hearts with the attire of the fear of God, your tongues with absolute truthfulness, your bodies with the vesture of courtesy. These are in truth seemly adornings unto the temple of man, if ye be of them that reflect. Cling, O ye people of Bahá, to the cord of servitude unto God, the True One, for thereby your stations shall be made manifest, your names written and preserved, your ranks raised and your memory exalted in the Preserved Tablet. Beware lest the dwellers on earth hinder you from this glorious and exalted station. Thus have We exhorted you in most of Our Epistles and now in this, Our Holy Tablet, above which hath beamed the Day-Star of the Laws of the Lord, your God, the Powerful, the All-Wise.
