The origins of this colorful festival were long ago, when
Indra, the king of the Gods (not of the Great Gods, like
Brahma/Vishnu/Shiva and the Goddess), who is also the God of Rain,
descended into this valley in a cloud of mist. He was disguised
as an ordinary mortal, and came here at the behest of his mother, who
needed some Parijat flowers for her Teej rites. It just so
happened that there was a dearth of those heavenly flowers in heaven,
but an abundance of them in this heavenly valley. Indra,
unfortunately, was caught stealing the flowers, and he was bound up and
put in a cage on public display. His mother got worried when he
didn't return with her flowers, and she came down in search of her
son. When she found him imprisoned, she explained to the people
the mistake they had made. Indra was immediately released, and
both he and his mother were worshipped and showered with flowers by the
abashed Kathmanduites, who instituted a yearly festival in Indra's
honor, in order to make it up to him.
Indra Jatra begins six days
before the official inauguration of the festival, with the search for a
pine tree in a special forests east of Bhaktapur. The tree, found
worthy of the task of being Indra's victorious standard
(dhvaja) is stripped of its bark and dragged for several days to
Kathmandu by men of the various towns along the way.
