An offering to the productivity gods

This is a drawing I did in 2007, when I was in India.  My goal when I was there was to learn something about the mythological nature of rivers, and so one thing that attracted me were the stories from the Bhagavata Purana that involved the Yamuna River.  In one of them, Krishna defeated the five headed serpent-demon Kaliya, who was living in the Yamuna and causing it to be poisoned.
