Yes all that is the earth-consciousness – mineral=matter, vegetable=the vital-physical creation, animal=the vital creation, man = the mental creation. Into the earth-consciousness so limited 
to mind, vital, matter has to come the supramental creation. Necessarily at first it cannot be in a great number – but even if it is only in a few at first, that does not mean that it will have no effect on the rest or will not change the whole balance of the earth-nature.
