When Arjuna got the pashupatastra from Shiva, other gods
also blessed him with more divine weapon. Varuna, the wind god gave him
dandastra; Kubera gave him the antardhyanastra; and Indra also asked
Arjuna to visit heaven and learn how to use the weapons. Indra's divine
chariot, drawn by hundred horses, took him to heaven. There, a number of
fairies demi-gods welcomed him. The gandharvas, heavenly musicians,
played melodious music for him. Arjuna stayed in Indra's palace and learnt
how to use the weapons, after which he wanted to go back to earth. But
Indra asked him to stay for more time and learn to play the divine music
of the gandharvas. Down on earth, the rest of the Pandavas were worried
about the well being of Arjuna. Soon Arjuna returned to them and showed
all the weapons that he received.
