Shuddhadvaita is an Indian philosophy that teaches that everything in the universe is one. It means that we are all connected and that everything around us is made up of the same thing. So, like Legos, all the bits and pieces are made of the same material, but we can build many different shapes and things with them. That's kind of like Shuddhadvaita – all parts of the universe are made of the same thing, but we can experience it in many different ways.
