Interestingly such ritual is common in Hinduism. Vesak Day is also known as Buddha Purnima, a full moon day that marks birth, enlightenment and also death (Final Nirvana) of the Gautama Buddha. Also interesting to see a baby Buddha statue. Both Buddhists and non-Buddhists were performing this ritual.

I find the backdrop for the worshipping materials interesting.

One of the sacred Buddhist temple that has distinctly Tibetan colors and housed a few thousands of images of Buddha (various kinds). Apparently built as a small temple around 600 CE.
