…consider, if among the people who are merely the
manifestations of the world of being this significant matter [co-operation,
mutual assistance and reciprocity] is of such importance, how much greater must
be the spirit of co-operation and mutual assistance among those who are the
essences of the world of creation, who have sought the sheltering shadow of the
heavenly Tree, and are favoured by the manifestations of divine grace; and how
the evidences of this spirit should, through their earnest endeavour, their
fellowship and concord, become manifest in every sphere of their inner and
outer lives, in the realm of the spirit and divine mysteries and in all things
related to this world and the next. Thus there can be no doubt that they must
be willing even to offer up their lives for each other.
