illusions

Sakuni also, conversant with a hundred different kinds of illusions, created illusions for confounding the two Krishnas. Then

1. clubs, and 
2. iron balls, and 
3. rocks and 
4. Sataghnis and 
5. darts, and 
6. maces, and 
7. spiked bludgeons, and 
8. scimitars, and 
9. lances, mallets, axes, and 
10. Kampanas, and 
11. swords, and 
12. nails, and 
13. short clubs, and 
14. battle-axes, and 
15. razors, and 
16. arrows with sharp broad heads, and 
17. Nalikas, and 
18. calf-tooth headed shafts, and 
19. arrows having bony heads and 
20. discs and 
21. snake-headed shafts, and 
22. spears, and 
23. diverse other kinds of weapons, fell upon Arjuna from all sides.  

And

1. asses, and 
2. camels, and 
3. buffaloes, and 
4. tigers, and 
5. lions, and 
6. deer, and 
7. leopards, and 
8. bears, and 
9. wolves and 
10. vultures, and 
11. monkeys, and 
12. various reptiles, and 
13. diverse cannibals, and 
14. swarms of crows, all hungry, and excited with rage, ran towards Arjuna. 

Then Dhananjaya, the son of Kunti, that hero conversant with celestial weapons, shooting clouds of arrows, assailed them all. And assailed by that hero with those excellent and strong shafts, they uttered loud cries and fell down deprived of life.

Then a thick darkness appeared and covered Arjuna's car, and from within that gloom harsh voices rebuked Arjuna. The latter, however, by means of the weapons called Jyotishka, dispelled that thick and awful darkness.

When that darkness was dispelled frightful waves of water appeared. For drying up those waters, Arjuna applied the weapon called Aditya. And in consequence of that weapon, the waters were almost dried up.

These diverse illusions, repeatedly created by Sauvala, Arjuna destroyed speedily by means of the force of his weapons, laughing the while. Upon all his illusions being destroyed, afflicted with Arjuna's shafts and unmanned by fear, Sakuni fled away, aided by his fleet, steeds, like a vulgar wretch.
