18. The rituals of the three vedas, are fluttering like the bees over the tree, blooming with the blossoms of beauteous women, and shaking with the oscillations of the mind; while it is corroded in the inside by the cankering worms of cares and actions. (It means to say, that the vedic rites, the love of women, the thoughts of the mind and the bodily actions, are all attendants of ignorance; and he is wise who refrains from them in toto).
19. The tree of ignorance, blossoming like the flowers of the garden of paradise, exhales the sweet odours of pleasure around; and the serpent of vice twining round it, leads the living souls perpetually to evil deeds, for the supportance of their lives.
20. It blooms with various flowers, to attract the hearts of wise; and it is fraught with various fruits, distilling their sweets all around. (These fruits and flowers are the sensual pleasures, which allure the ignorant to them).
21. With the aqueducts about, it invites the birds of the air to drink of them; and being besmeared with the dust of its flowers, it appears to stand as a rock of red earth or granite to sight. (The water beds below it, are mistaken for the salsabil or streams of Paradise, and its rock-like appearance, shows the grossness of ignorance crasse or tabula rasa).
22. It shoots out with buds of mistakes, and is beset by the briars of error; it grows luxuriant in hilly districts, with exuberance of its leafy branches. (Meaning that the hill people are most ignorant).
23. It grows and dies and grows again, and being cut down it springs out anon; so there is no end of it. (It is hard to extirpate ignorance at once).
24. Though past and gone, yet it is present before us, and though it is all hollow within, it appears as thick and sound to sight. It is an ever fading and ever green tree, and the more it is lopped and cropt, the more it grows and expands itself.
25. It is a poisonous tree, whose very touch benumbs the senses in a moment; but being pressed down by reasoning, it dies away in a trice.
26. All distinctions of different objects, are dissolved in the crucible of the reasoning mind; but they remain undissolved in their crude forms in the minds of the ignorant, who are employed in differentiating the various natures of men and brutes, and of terrene and aquatic animals.
27. They distinguish the one as the nether world, and the other as the upper sky; and make distinctions between the solar and lunar planets, and the fixed starry bodies. (But there are no ups and downs, nor any thing as fixed in infinite vacuity).
