[Extract from a Tablet of 'Abdu'l‑Bahá]
In this day, no greater manifestation of love and kindness can be conceived in the world of existence than this, that, at the Shrine of Bahá'u'lláh, one should call to mind a loved one, make mention of him, and offer prayers for his well-being. This is God's mightiest favour, His greatest bounty, His highest gift, and the sign of His consummate bestowal.
---'Abdu'l‑Bahá
