'Book of Creativity' is my English translation of Sefer Yesira, an ancient Hebrew mystical text, foundational to Kabbalah, that first promulgated the concept of combinatorial creativity. Sefer Yesira's cryptic text weaves together the 22 elemental Hebrew letters and 10 enumerations whose combinations and permutations purport to enmesh the bedrock and spring of all worlds, experiences and languages. It is important not just for having a catalytic effect on the creativity of major historical figures like Abraham Ablulafia and Giovanni Pico della Mirandola but also for a seminal influence germinating the seeds of modern logic and computing into the looming Golem of AI today.
