17. Reason displays the darkness of ignorance, and shows the state of the Supreme as clearly, as when the light of the lamp shows everything clearly in the room. (Hence reason is said to be the light of the soul). 18. The light of knowledge dispels the gloom of sorrow, as the solar light puts to flight the shadow of night. (Knowledge is the sunlight of the soul). 19. Upon appearance of the light of knowledge, the knowable comes to appear of itself; as the appearance of sunlight in the sky, shows every object on earth below. 20. That science which brings to the knowledge of Divine Truth, the same knowledge is known as self-same with the knowable Truth itself. 21. Spiritual knowledge is the result of reason, and is reckoned as the only true knowledge by the wise; it includes the knowledge of the knowable soul, as the water contains its sweetness within itself. 22. The man knowing all knowledge, becomes full of knowledge; as the strong dramdrinker turns a tippler himself. (Fullness of spiritual knowledge is compared with hard drinking, in the mystic poetry of orientals, to denote the inward rapture which is caused by both). 23. They then come to know the knowable, supreme spirit as immaculate as their own souls; and it is only through the knowledge of the supreme spirit, that this rapture imparts its grace to the soul. 24. The man fraught with perfect knowledge, is full of his unfailing rapture within himself, and is liberated in his life; and being freed from all connections, reigns supreme in the empire of his mind. (This refers equally to a savant in all knowledge, to a deep philosopher, as also to a holy man; a yogi and the like). 25. The sapient man remains indifferent to the sweet sound of songs, and to the music of the lute and flute; he is not humored by the songstresses, and by the allurement of their persons and the enticement of their foul association. 26. He sits unaffected amidst the hum of buzzing bees, fluttering joyfully over the vernal flowers; and amidst the blooming blossoms of the rainy weather, and under the growling noise of the roaring clouds. 27. He remains unexcited by the loud screams of the peacock, and the joyous shrill of storks at the sight of fragments of dark clouds; and by the rolling and rumbling of the gloomy clouds in humid sky. 28. He is not elated by the sound of musical instruments, as that of the jarring cymbal or ringing bell held in the hands; and the deep rebellowing drum beaten by the rod; nor the wind, wired or skinned instruments can act upon his mind. 29. He turns his mind to nothing that is sweet or bitter to taste, but delights in his own thoughts; as the moon sheds her light upon the spreading lotus-bud in the lake. 30. The wise man is indifferent to the attractions of beauties and celestial nymphs; who are as graceful in their stature and attire, like the young shoot of the plantain tree with its spreading foliage.
