The human being's divine striving : manas, buddhi, atman

Rudolf Steiner:  "In that all men are brothers, there they find themselves to be at one.... That force which is common to all mankind, which expresses itself in the intellectual as an all-embracing unity about which there can be no conflict, is called Manas. And when men have progressed so far that they are not only at one in their intellect, but also in their perceptions and feelings, and are in harmony in their inmost souls, so far that they find themselves in what is noble and good, so far that they lovingly join together in the objective, in what they have in common, in the same way that they agree that two times two makes four and three times three equals nine; then the time will have arrived when men will be able to control the living as well. Unanimity — objective unanimity in perception and feeling — with all humanity really embracing in love: such is the pre-condition for gaining control over the living. Those who founded the movement of the Holy Grail in the twelfth century said that this control over living [nature] was at one time available, available to the gods who created the cosmos and descended [to Earth] in order to give mankind the germ of the capacity for the same divine forces that they already possessed themselves; so that man is now on the way to becoming a god, having something in his inner being which strives upwards towards where the gods once stood. Today, the understanding, the intellect, is the predominant force; in the future it will be love [Buddhi], and in a still more distant future, man will attain the stage of Atman."
