Ganga Dashahara
What it is
Ganga Dashahara falls on the tenth lunar day of the bright half of Jyeshtha — Jeth Sud Dasham — in the very heart of summer. It commemorates the avataran, the descent, of Shri Gangaji from the heavens to the earth. The Puranas tell of King Bhagirath, who performed generations-long tapasya so that his ancestors might be liberated; moved by his devotion, Gangaji agreed to come down, and Shri Mahadev received her torrent in his matted locks so that the earth could bear her force. The very name carries her promise: 'Dashahara' means 'destroyer of the ten sins', and bathing in her waters on this tithi is held to cleanse the faults of body, speech and mind.
Across India the day is kept with snan in the river, deepdaan on her banks, and grateful worship of Ganga as mother. Because it arrives when the heat is at its fiercest, the utsav belongs naturally to the season of water — of cooling baths, fountains and riverside leela — and that is precisely the mood in which the havelis of Pushtimarg receive it.
Why we observe it
For a Pushtimarg Vaishnav, the great rivers are not merely tirthas; they are divine swarups. First among them is Shri Yamunaji, the fourth beloved of Shri Krishna, and Shri Mahaprabhuji sings in the Shri Yamunashtakam that even Gangaji's glory becomes complete through her sangam with Shri Yamunaji, whose grace bestows the gift of bhakti itself. So on Ganga Dashahara the haveli's bhav turns to water as the playground of Prabhu's leela.
In many houses of the sampradaya the day brings jal vihar and the beloved naav manorath: Shri Thakorji is seated in a boat upon filled water, lotuses and little floating toys are set adrift before him, and the sevaks' hearts become gopis sporting with their Lord in the cool of the river. There is a tender teaching inside all of it: in the burning days of Jyeshtha, the Vaishnav's first thought is Prabhu's comfort — cool water, sandalwood, fragrant khas. To observe Ganga Dashahara is to thank the sacred rivers for their grace, and to remember that for the bhakta every river finally flows toward one place: the leela of Shri Krishna.
