6. The Divine and the Hostile Powers
Where do you find in “The Life Heavens”1 that I say or anybody says the conditions on the earth are glorious and suited to the Divine Life? There is not a word to that effect there! The Life Heavens are the heavens of the vital gods and there is there a perfect harmony but a harmony of the sublimated satisfied senses and vital desires only. If there is to be a Harmony, it must be of all the powers raised to their highest and harmonised together. 
All the non-evolutionary worlds are worlds limited to their own harmony like the Life Heavens. The Earth, on the other hand, is an evolutionary world, not at all glorious or harmonious even as a material world (except in certain appearances), but rather most sorrowful, disharmonious, imperfect. Yet in that imperfection is the urge towards a higher and more many-sided perfection. It contains the last finite which yet yearns to the supreme Infinite, (it is not satisfied by sense-joys precisely because in the conditions of the earth it is able to see their limitations). God is pent in the mire (mire is not glorious, so there is no claim to glory or beauty here), but that very fact imposes a necessity to break through that prison to a consciousness which is ever rising towards the heights. And so on. That is “a deeper power”, though not a greater actual glory or perfection. All that may be true or not to the mind, but it is the traditional attitude of Indian spiritual experience. Ask any yogin, he will tell you that the Life Heavens are childish things; even the gods, says the Purana, must come down to earth and be embodied there if they want mukti, giving up the pride of their limited perfection; they must enter into the last finite if they want to reach the last infinite. A poem is not a philosophical treatise or a profession of religious faith – it is the expression of a vision or an experience of some kind, mundane or spiritual. Here it is the vision of the Life Heavens, its perfection, its limitation and the counter-claim of the Earth or rather the Spirit or Power behind the earth-consciousness. It has to be taken at that, as an expression of a certain aspect of things, an expression of a certain kind of experience, not of a mental dogma. There is a deep truth behind it, though it may not be the whole truth of the matter. In the poem, also, there is no question of a divine life here, though that is hinted at as the inexpressed possible result of the ascent – because the Earth is not put aside (“Earth’s heart was felt beating below me still”); nevertheless the poem expresses only the ascent towards the Highest, far beyond the Life Heavens, and the Earth-Spirit claims that power and does not speak of any descent of a divine life.
