A bamboo pole with baskets or receptacles dangling from either end is known as a kanvar.
A kanvar would have
been a natural means for humans to transport big things in the past.
Its most common use nowadays is for religious ceremonies in
which pilgrims transport water from one location to another to present to a
god.
The kanvar is the mechanism that keeps the water raised
during the journey.
This maintains the water's natural purity, retaining it as a
suitable tribute to a god.
The temple of Vaidyanath in Bihar is the most well-known
example of this procedure.
It's also found at temples in Uttar Pradesh's Haridwar, West
Bengal's Tarakeshvar, and Maharashtra's hills.
