|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
atha vyavasthitan drishtva
dhanur udyamya pandavah
hrishikesam tada vakyam
idam aha mahi-pate
At that time Arjuna, the son of Pandu, seated in the chariot bearing the flag marked with Hanuman, took up his bow and prepared to shoot his arrows. O King, after looking at the sons of Dhritarashtra drawn in military array, Arjuna then spoke to Lord Krishna these words.
This is the last of the verses that shows the auspicious arrangements made by Krishna for His devotees. On the chariot flag of Arjuna, Hanuman was personally present. Once when Bhima was charging up a mountain to fetch a thousand-petalled lotus for Draupadi, he was stopped by a small monkey lying on his path. Despite many requests from Bhima the monkey refused to move out of this path. The angered Bhima then tried to pick the monkey's tail up but was astonished that despite exerting himself fully he could not even budge the tail. Finally the monkey revealed himself to be Hanuman the elder brother of Bhima (since both were offspring's of Vayu, the wind God). Hanuman then embraced Bhima and gave him the benediction that he would be personally present on the flag of Arjuna's chariot and whenever Bhima would shout his war cries he would join him also. It is said that the combined cries of Bhima and Hanuman were so terrifying that elephants would stampede and even great warriors would shake with fear. In the previous yuga, Lord Rama and Hanuman and vanquished the evil Ravana. Krishna is always accompanied by His servitor (Hanuman) and consort (Goddess of good fortune). Now since they were again present in Kurukshetra, the defeat of the Kauravas and good fortune of the Pandavas is assured. Krishna as Hrishikesa has taken the position of directing His devotees the Pandavas. Srila Prabhupada summarize this in his purport as follows, "In such auspicious conditions, arranged by the Lord for His eternal devotee, lay the signs of assured victory."
