A demon giant, seen lying beyond Rama’s pavilions, blocks the river’s water with his body.

The fanged demon lies on his side on the ground while holding his huge sword in his right hand. Rama’s group is visible in the foreground as they wait in a Siamese-style royal pavilion for the medicine they need to heal Laksman.
