midnight
`` Thou shalt , Hans Rudolph von Bischofswerder . The grand master of our order will bestow upon thee this happiness , and to-night shall the star of the future rise over thee . Hold thyself in readiness . At midnight , present thyself at the first portal of the royal palace in Berlin . A man will meet thee , and thou shalt ask , ` Who is our hope ? ' If he answers thee , ` The Prince of Prussia , ' then he is the messenger which I shall have sent thee -- follow him . Bow thy head in humility , shut thine eyes to all earthly things , turn thy thoughts inward , and lift them up to the great departed , which hovers over thy head , and speak with the blue flame which glows upon thy brow !
