Satush Kumar was born in Rajasthan, India, where the Peacock, the Mayura, is a sacred bird and also associated with the monsoon. In India, it is believed that after the long, hot summer peacocks come out and display their bright and vibrant feathers in an extravagant dance to please Indra, the god of rain, before calling to let the rains begin, bringing relief to plants, animals, soils and humans.
