瑜伽論記 14.271

14.271

泰云：由修平等無有自他無大小觀，名等心天，由久修無大小故，住一毛端空量，由久修無彼此故，更互不相妨礙。

Tai says: Because they cultivate the contemplation of equality, lacking self and other, and lacking large and small, they are called Equal-Minded Devas. Due to long cultivation of the absence of large and small, they dwell within the space of a single hair's tip; due to long cultivation of the absence of this and that, they do not mutually obstruct one another.
