The Truth means fact! Truth means the future of Henry Marlon and many secrets because The Truth contains the life-death cycle of Henry. But if The Truth falls into the hands of some other person, then that person will be able to reveal the existence of Henry by misusing the book. It is quite possible that due to this, Henrys life can prove to be meaningless. Similarly, if anyones blood comes in contact with The Truth, then that person can precisely read the future of Henry Marlon.
