With regard to your question concerning contributions to the Temple fund: the friends should certainly be encouraged and even urged to support financially this, as well as other national institutions of the Cause. But they should, under no circumstances, be required to do so. As to the idea of “giving what one can afford”: this does by no means put a limit or even exclude the possibility of self-sacrifice. There can be no limit to one's contributions to the national fund. The more one can give the better it is, especially when such offerings necessitate the sacrifice of other wants and desires on the part of the donor. The harder the sacrifice the more meritorious will it be, of course, in the sight of God. For after all it is not so much the quantity of one's offerings that matters, but rather the measure of deprivation that such offerings entail. It is the spirit, not the mere fact of contributing, that we should always take into account when we stress the necessity for a universal and whole-hearted support of the various funds of the Cause.
on behalf of Shoghi Effendi, 31 December 1935 to Mrs. Ethel Furbush
