18. The physical sphere contains all created beings, and extends to the circuit of the ten sides, all about and above and below us. It is a continued space filled with air, which supports the clouds and waters above the firmament. 19. Then the vacuity of the mental sphere, which has also sprung from the intellectual sphere, has likewise the intellect for its cause like the others, as the day is the source of all works and animal activities. (Here the word works has the double sense of the works of creation, which were made in the week days, and the daily works of men and their religious duties, all which are done in the day time. The night being the time to sleep). 20. The vitiated Intellect which views itself as a dull thing, amidst the gross material objects of the physical sphere, the same is termed the mind, which thinks of both spheres, whence it is born and where it is placed. 21. It is for the understanding of the unenlightened, that I have made use of the metaphor of the spheres; because figures are used for the instruction of the unenlightened and not to lighten the enlightened. (These serve for ocular demonstrations in mathematical and not in metaphysical sciences). 22. In the intellectual sphere, you will see one Supreme Brahma, filling its whole space, and being without parts or attributes, and intelligible only to the enlightened. 23. The ignorant require to be instructed in appropriate words and precise language, showing the demarkation between monotheism and ditheism, which is unnecessary for the instruction of the enlightened. 24. I have contrived to explain to you the nature of divine knowledge, by the parable of the three spheres, which will enlighten you as long as you are in dark on the subject. 25. The intellectual sphere being obscured by ignorance, we are led to look into the mental and physical spheres; not knowing that they are as delusive as the sunbeams in a mirage, and as destructive as the flames of a conflagration. 26. The pure intellect being changed to the state of the changeful mind, takes a debased figure; and then being confounded in itself, weaves the magic web of the world to entangle itself in the same. [10]27. The ignorant that are guided by the dictates of their perverted minds, know nothing concerning the nature of the Intellect, which is identic with the Supreme. So the witless that unwittingly take the white shells for bright silver, are seen to labour under their delusion, until they are freed from it, by the clear light of their understanding.
