… those who deliver the Message should travel to all parts of the country. And if delivering the Message should be the cause of disturbance, let them then be engaged in encouraging and educating the friends, in order that those souls receive spiritual attraction and rejoice, seek delight and ecstasy, acquire new life and through the fragrances of sanctity gain vivacity and freshness.

The object is this, that in the time of peace and safety this work of delivering the Message should be carried on with the utmost fervor. But when there is no peace and safety, extreme wisdom should be exercised, though no complete cessation of effort is permissible, for in that case the divine assistance shall be entirely cut off.
