19. So is this formal world a visible representation of the thoughts or workings of the mind, it is as an exquisite performance of the mind of the artist, from the prototype ingrafted in the soul. 20. It is the apparition of an unreality, and is present in appearance but absent in substance; it is verily the appearance of an unreality, by whatever cause it may have come to appear. (The Cause is said to be the original ignorance or delusion (_ádi-avidyá or máyá_)). 21. It is as the sight of the forms of ornaments, in the same substance of gold; and the vault of the world, is as full of ever changing wonders, as the changeful and wondrous thoughts of the mind. Wherefore it is the cessation of thought, that causes the extinction of the world. (Nothing exists to us whereof we have no thought). 22. Hence it lies entirely in your power, to have or leave the world as you may like; either disregard your temporal enjoyments, if you have your final liberation; or continue in your acts and rites, in order to continue in your repeated transmigrations through endless births and deaths. 23. I understand you have attained your state of rationality; and have purified your soul in this your second or third stage of Yoga; I believe you will not fall back or come down to a lower order, therefore hold your silence and rely in the purity of the soul and shut out invisibles from your sight. CHAPTER IX. ON THE DEVELOPMENT OF INTELLECT. Argument:—Description of the Intellect, as cause of the appearance and disappearance of the World. Bhusunda said:—The unintelligible objects of thought are phenomena of the intellect; they lie as calmly in the great mass or inert body of the intellect, as the sunbeams shine in the bosom of a clear basin of water (where they retain their light without their heat). 2. The unintelligent world subsists in the intelligent intellect, by its power of intellection; and remains alike with the unlike (_i.e._ matter with the mind), as the submarine fire resides in the water, and the latent heat with cold. 3. The intelligent and the unintelligent (_i.e._ the subjective I and the objective—these) have both their source in the intellection of the intellect, which produces and reduces them from and into itself, as it is the same force of the wind, which kindles as well as extinguishes the fire. 4. Do you rest in the intellect, which remains after negation of your egoism (which is the cause of both the subjective and the objective): and remain in that calm and quiet state of the soul, which results from your thinking in this manner. (_i.e._ By forgetting yourself, you forget everything else besides the wakeful intellect). 5. Thou art settled in thy form of the intellect, both within and without every thing; as the sweet water remains in and out of a raining cloud. (The gloss explains it saying that, after you are freed from all thoughts, you see the sole Brahma only).
