Vijayadashami (Dussehra)
What it is
Vijayadashami, the tenth day of Ashwin Sud, is Nav Vilas's culmination and, across India, is kept as the day good overcomes evil, most widely remembered through Ram's victory over Ravana. In Pushtimarg its own particular observance centres on the jav sown on the first day of Nav Vilas: by now grown into jawara (young shoots), it is tied with red silk thread and, during Uttapan, the finest shoots are chosen and set into Shrinathji's own shringar upon His head that evening.
Jawara and tulsi are then offered at His feet, and during Sandhya Aarti the day's utsav bhog includes Das Maat, offered in the bhav of ten known Bhaktas, ten devotees remembered together on this day of culmination.
Why we observe it
Vijayadashami closes the arc Nav Vilas opened: the barley sown as a bare seed on day one, watched and tended through nine days precisely because Navdha Bhakti itself has to be tended, is not discarded once it has grown but is offered back, worn in Shrinathji's own shringar. Devotion that ripens is given straight to Prabhu, not kept.
A Vaishnav can hold both threads of the day at once: the wider, pan-Hindu sense of a victory won, and Pushtimarg's own quieter reading, that what was planted in devotion on the first day of these ten does not vanish, it is grown, gathered and returned.
