成唯識論演祕 6.181

6.181

作觀行者而依空定，觀境皆空；若餘人等，即於其境而為其實，既互相違，明境隨心種種見別。

A practitioner of contemplation relies on the concentration on emptiness and contemplates objects as entirely empty; whereas other people take those very objects to be real. Since they mutually conflict, it is clear that objects follow the mind and differ according to various perceptions.
