The text, translated into English, formed the ninth section of an experimental work entitled Zangezi, published in Moscow in 1922. Here, Khlebnikov rings a series of changes on the Russian word for mind (um, pronounced oohm), adding to it conventional as well as invented prefixes. His glossary of the resulting neologisms is also printed on the back cover. This book was printed on the occasion of the 11th International Sound Poetry Festival in Toronto, 1978. -- Source of annotation: Marvin or Ruth Sackner.

The calligraphic works are dense, difficult to read, overwritings that give abstract images somewhat similar to the early poetic calligraphic poems by Carlfriedrich Claus. -- Source of annotation: Marvin or Ruth Sackner.
