Binayak is a common alternative name of Ganesh, the elephant headed God. Son of lord Shiva, he is believed to manifest good luck and hence is he worshipped first in almost all religious and auspicious occasions. This particular one, Karya Binayak, directly translates to ‘Work Ganesh’ (Karya = Work, Binayak = Ganesh). Before people begin any work, project and any new endeavour, they often worship Karya Binayak first. As guided by faith, Tuesday and Saturday are regarded as
auspicious days to visit the temple.
Every year in Mangsir Purnima (full moon night in the month of Mangshir in Nepali calendar), a ceremony is held that requires worshipping both Rato Machindranath and Karya Binayak at very same auspicious date and time; the liturgy can be witnessed in Bungamati. Karya Binayak is brought to Rato Machindranath and revolved three times around the temple and then the Binayak is taken to the Priest’s home. This is an indication of the end of the Jatra.
