Extract from a Tablet of ‘Abdu’l‑Bahá
As to the Nineteen Day festivity, it is of the utmost importance that the friends should gather at a meeting where, in complete attunement and love, they should engage in the remembrance of God and His praise, and converse as to the glad-tidings of God, and proofs of the advent of Bahá’u’lláh, and should recount the high deeds and sacrifices of the lovers of God in Persia, and tell of the martyrs’ detachment from the world, and their ecstasy, and of how the believers there stood by one another and gave up everything they had.
The Nineteen Day festivity is, therefore, of very great importance.
