User blog:Dark Paladin X/Om Mani Padme Hum

Om Mani Padme Hum is a Tibetan unique tech that can be researched in the Castle in the Imperial Age. Once researched, it changes the Monk cost from 100 gold to 100 food instead, making Tibetan monks trash units.

Strategy
Om Mani Padme Hum allows the Tibetans to fully transition into Monks late game. With Monks costing food instead of gold, combined with the Tibetan civilization bonus of Monastery techs costing food instead of gold and faster Moanstery work rate, this makes spamming Monks incredibly viable for the Tibetans lategame when gold runs low. Nevertheless, Monks in the Imperial Age are considered to be utility units (especially in team games where gold isn't an issue thanks to a stable trade line), as massing up Monks and converting units still requires a lot of micromanagement. Regardless, having Monks cost food allow the player to save up a lot of gold that can be used to train cavalry units, especially the fact that the Tibetans do not get Bloodlines and giving their Stables units more survivability lategame..
