What did Piet Mondrian mean by using art to create a harmonious vision of life?

Piet Mondrian believed that art could serve as a guide for humanity, moving beyond the depiction of arbitrary, everyday appearances to establish a new, harmonious vision of life. By utilizing a strict, formal language of straight lines, right angles, and primary colors, he sought to transcend personal temperament and momentary visual perceptions.123

For Mondrian, this pursuit was deeply rooted in his theosophical beliefs and a desire to express a "pure" reality. He viewed his work as a means to embody a harmonious cosmos, aiming to derive compositions from abstract geometric rules rather than fragments of nature. By creating this "Utopia" of clarity and force, he intended for his art to function as a universal language, conveying a spiritual message that could offer a more balanced and orderly perspective on existence. Ultimately, his commitment to this extreme formal purity was an ethical endeavor, intended to replace the chaos of the external world with a vision of universal harmony.1423
