In connection with the institution of the National Fund and the budgetary system set forth in the minutes of the National Spiritual Assembly, I feel urged to remind you of the necessity of ever bearing in mind the cardinal principle that all contributions to the Fund are to be purely and strictly voluntary in character. It should be made clear and evident to every one that any form of compulsion, however slight and indirect, strikes at the very root of the principle underlying the formation of the Fund ever since its inception. While appeals of a general character, carefully-worded and moving and dignified in tone are welcome under all circumstances, it should be left entirely to the discretion of every conscientious believer to decide upon the nature, the amount, and purpose of his or her contribution for the propagation of the Cause. (Shoghi Effendi, from a letter dated 10 January 1926 to the National Spiritual Assembly of the United States and Canada, published in "Bahá'í Administration"; The Compilation of Compilations, vol. I, Baha’i Funds and Contributions)
