'five natures distinction.' A theory of the Yoga^ca^ra 瑜伽行派 school that teaches the discrimination of the innate capacities of temperaments of sentient beings into five types， these being: （1） the nature predetermined for /sra^vaka 声闻; （2） the nature predetermined for pratyekabuddha 辟支佛; （3） the nature predetermined for bodhisattva 菩萨; （4） the indeterminate nature 不定性， and （5） the nature lacking capacity for enlightenment （一阐提 icchantika）. This theory was one of the points of contention by which indigenous East Asian schools such as Huayan disagreed with Yoga^ca^ra.
