Letters of Sri Aurobindo
Volume III - Part 4
The Self governs the diversity of its creation by its unity on all the planes from the Higher Mind upwards, for there some realisation or vision of the One Truth or the Universal is the natural frame and basis of the whole consciousness. But the higher one rises upward, the more the spiritual view changes, the power of consciousness changes, the Light becomes ever more intense and potent. The essential static realisation of Infinity and Eternity and the Timeless One remains the same, but the vision of the workings of the One becomes ever wider and is attended with a greater instrumentality of Force and a more comprehensive grasp of what has to be known and done. All possible forms and constructions of things become more and more visible, more perfectly put in their proper place, more luminously utilisable. A clear spacious thought-knowledge in the Higher Mind becomes a mass of illuminations in the Illumined Mind and heightens into direct intimate vision on the Intuition level. But the Intuition sees in flashes and combines through a constant play of light 
– through a chain or coordinated harmony of revelations, inspirations, intuitions, swift discriminations. The Overmind sees calmly, steadily, in great masses and deep and large extensions of space and time and relation, globally, in wholes; it has the universal touch not only in spirit but in its manner. It creates and acts in the same way – for the Overmind is the world of the great Gods, the divine Creators. But each Godhead creates in his own way; he sees all but that all is seen from his own divine viewpoint. There is not the absolute supramental harmony and certitude. These are some of the differences. I speak of these planes in themselves – for when they act in the human consciousness, they are necessarily much diminished in their working, for they have to work with and depend on the human instrumentation or man’s smaller seeking mental intelligence, his passionate turbid vital and mental, his cabined and narrow physical intellect – their workings get badly mixed up with these inferior modes of consciousness and their diluted light of ignorance. Only when these lower impotencies are quieted can those higher powers get a fuller force and reveal more of their original luminous character.
