Why did Gaudi use organic curving shapes instead of straight lines?

Gaudí favored organic curving shapes because they mimic the forms found in nature, which he believed embodied beauty and harmony. These shapes allowed him to create fluid, dynamic structures that were both aesthetically pleasing and structurally sound. By avoiding straight lines, he aimed to break away from traditional architectural constraints and evoke a sense of movement and life in his designs. This approach also reflected his deep spiritual connection to nature and his desire to integrate architecture with the environment.
