Akshauhini

Darkness having enveloped the world during that fierce battle, the entire Pandava army, with Savyasachin, the son of Panda, could
not be seen. We had never before, O king, heard of or seen the like of that weapon which Drona's son
created in wrath on that occasion. Then Arjuna, O king, invoked into existence the Brahma weapon,
capable of baffling every other weapon, as ordained by the Lotus-born (Brahma) himself. Within a
moment that darkness was dispelled, cool winds began to blow, and all the points of the compass
became clear and bright. We then beheld a wonderful sight, viz., a full Akshauhini (of the Pandava
troops) laid low.  Burnt by the energy of Aswatthaman's weapon, the forms of the slain could not be
distinguished.
