“Thy letter hath reached this captive of the world in His prison. It brought joy, strengthened the ties of friendship, and renewed the memory of bygone days. Praise be to the Lord of creation Who granted us the favour of meeting in the Arabian land,¹ wherein we visited and held converse. It is Our hope that our encounter may never be forgotten nor effaced from the heart by the passage of time, but rather that, out of the seeds thus sown, the sweet herbs of friendship may spring forth and remain forever fresh and verdant for all to behold...”

– Bahá’u’lláh, The Tabernacle of Unity
