Sanatan was born and brought up in a remote Bengal village and finds himself deeply rooted and inspired by his rural background. He states, “My art practice is a creative journey opening itself into an infinite visual space gleaming with memories, images, colours, and spaces. These images are entirely personal yet universal owing to their aesthetic promise and poignant qualities. Generally speaking, my paintings convey a luminous pictorial world replete with innumerable images emerging from various layers of the painted surface. These layers perhaps correspond to our layered existence and memories of past as well as present. What apparently seems to be a journey down the memory lane is actually a very tangible reality for me”.
