"February 12, 1900, supp. vol. You might think, “What if I lose everything as a result of carrying out contribution, which may entail going through hardships and difficulties?” However, the truth of your contribution will endure for a lifetime and for eternity. The truth of delight in your mind will be accepted by Heaven. Listen and understand well. A human being lives only for a lifetime and cannot be said to live forever. However, you can take delight if I tell you that the mind is eternal. The truth of your contribution cannot be allowed to go unnoticed or be abandoned—such is the truth. The truth for eternity cannot be allowed to go unnoticed or be abandoned, because its effectiveness builds gradually year after year."
