The most unique book in all of Rubinshtein's Hebrew Quadrilogy and generally of his books -- "Bread, Water and Book" is a smaller, poetry-written like book that mostly discusses asceticism, semi-retirement from general society, and the ascention of one's self beyond the tyrrany of monetary passion and lust. Although an atheist, this is probably Rubinshtein's most "religious" books thus far. Available in Hebrew.
