Remember that an increase in knowledge is not the same as expanding the consciousness. Unless one expands his consciousness, he cannot use his knowledge for the good of all humanity and the whole Universe.
A materialistic scientist is not aware of Higher Worlds and their relationship to the events happening on earth. His vision is limited; his judgement is horizontal, and therefore he is doomed to failure. Unless every action is considered in relation to Higher Worlds and the distant future, man is condemned to failure or even to suicide.
