April 3

The Nineteen-days Feast has the utmost importance, that the beloved ones may gather in a meeting, be occupied with the utmost love and fellowship in mentioning the name of God, and speak about the glad tidings of God, deliver the proofs and evidences of the appearance of Baha'u'llah, mention the praiseworthy deeds and the sacrifices endured by the believers of God in Persia, talk about the severance and the attraction of the martyrs and remember the cooperation and the mutual assistance of the friends. Therefore this Nineteen-day Feast is most important.
