Mt. Meru?

Anybody know why Erv calls Pascal's triangle "Mt. Meru"?

This guy apparently has precedence:

Nevermind- Wikipedia to the rescue!

"The earliest explicit depictions of a triangle of binomial
coefficients occur in the 10th century in commentaries on the
Chandas Shastra, an Ancient Indian book on Sanskrit prosody
written by Pingala between the 5th and 2nd century BC.
While Pingala's work only survives in fragments, the
commentator Halayudha, around 975, used the triangle to
explain obscure references to Meru-prastaara, the
"Staircase of Mount Meru". It was also realised that the
shallow diagonals of the triangle sum to the Fibonacci numbers."

It's pretty cool that Erv knew this already in 9 BWE (Before
Wikipedian Era).
