Nelumbo is set upon a time where the current rash and busy world meets up with a time where people revere nature. The concept of how nature should be respected and worshiped instead of exploiting it for greedy needs is depicted in this movie. It tells the story of how nature can inspire humans to understand the cosmic reality and break away from the chain of illusions.—Yadu Vijayakrishnan
