The 37th Mandala is a horror novel written by Marc Laidlaw and published in 1996. It tells the story of New Age writer Derek Crowe who uses an ancient mystical text as the basis of one of his works. As his writing gains popularity, it also attracts the unwanted attention of the 37 mandalas — terrible Lovecraftian-style monsters — that the original text was about.
