Printing
The Buddha taught some people the teachings of duality that help them avoid sin and acquire spiritual merit.
To others he taught non-duality, that some find profoundly frightening.

Nagarjuna

Printing continues day and night

Four printers keep two presses running 24 hours a day to print Tibetan texts, while a third press prints English books half the year and the Tibetan texts the other half. A fourth press is specialized for printing the texts for prayer wheels. Every day we supply our presses with 4 tons of paper! The texts are printed on high quality acid-free paper to last three hundred years.
