Now the time has come that humanity, after its contemplation on material gain, must contemplate on another gain. Material gains are taken away in a moment's time and leave man in his grave alone without any of them. This earth has not even kept the wealth of the Pharaohs, so near to their heart; after so many years the wealth which was buried with them has been taken from them. It shows that this world has never allowed anyone to have his belongings for ever. It is a disappointing world; the true consolation of man does not belong to the earth or its knowledge. This does not mean that the knowledge of the world is useless, but the knowledge of the world does not suffice the whole purpose of life.
