makṣikāṇāṃ ca saṃghātā anugacchanti kauravān || 18 ||

The spot on the lunar disc hath changed its position; and Rahu also approacheth towards the sun. Meteors are falling from the sky with loud noise and trembling motion. The elephants are sending forth frightful cries, while the steeds, O Madhava, are shedding tears, without taking any delight in food and drink. They say, O thou of mighty arms, that on the appearance of these portents, a terrible calamity approacheth, productive of a great slaughter. O Kesava, amongst the steeds, elephants and soldiers, in all the divisions of Duryodhana's army, it is seen, O slayer of Madhu, that while small is the food these take, ample is the excreta they evacuate. The wise have said that this is an indication of defect. The elephants and steeds of the Pandavas, O Krishna, all seem to be cheerful, while all the animals wheel along their right. This also is an indication of their success. The same animal, O Kesava, pass by the left side of Duryodhana's army, while incorporeal voices are constantly heard (over their heads). All this is an indication of defeat. All auspicious birds, such as peacocks, swans, cranes, Chatakas, Jivajivas, and large flights of Vakas, follow the Pandavas, while vultures, Kankas, hawks, Rakshasas, wolves and bees, in flights and herds, follow the Kauravas. The drums in the army of Dhritarashtra's son yield no sounds, while those of the Pandavas yield sounds without being struck.
