Critical reception
Ian Mathers of Stylus Magazine gave the album a grade of "A", writing, "I'd say this is one of the finest 'imaginary soundtracks' ever released if I could just think of a film that wouldn't seem hideously overpowered by it."

Shawn Dspres of The Japan Times commented that "Although broken down into distinct parts, the seamless transition between tracks makes the album play out like one extended, breathtaking piece."

Thom Jurek of AllMusic gave the album 3.5 out of 5 stars, calling it "puzzling, bewildering and utterly beautiful."

In February 2007, American webzine Somewhere Cold voted Palmless Prayer / Mass Murder Refrain No. 7 on their 2006 Somewhere Cold Awards Hall of Fame.
