Planners of the Erdene Zuu monastery attempted to create a surrounding wall featuring 108 stupas. The number 108 is a magical and sacred number in Indian tradition, which also symbolizes perfection. There are 108 distinctive signs of perfection that distinguish a Buddha from other human beings.
108 is also the sum of the numbers (4, 8, 15, 16 , 23, 42) on one of my favorite TV shows, Lost. Not to mention, the number of minutes in the countdown at the Swan station before the numbers had to be input into the computer and a whole host of other appearances throughout the series.
