Holy Ruhnama is not sold at Amazon yet, but it’s mentioned in a book:
on Page 155:
“… Sometime after my visit, Turkmenbashi renames the days of the week and the months of the year after himself, the Ruhnama, his mother, and anything else he likes. Mondays are now called Turkmenbashi. …”
Oooh, I had a bad case of Turkmenbashis yesterday.
