大乘義章 1.110

1.110

若依《維摩》，眾生空者名為無我，法體空者名之為空。故彼經言「眾生是道場，知無我故；一切法是道場，知法空故。」空與無我，眼目之異，左右名之皆得無傷。名義如是。

According to the Vimalakīrti, the emptiness of sentient beings is called selflessness, and the emptiness of the substance of dharmas is called emptiness. Therefore that sūtra states: 'Sentient beings are the site of enlightenment, because one knows they are selfless; all dharmas are the site of enlightenment, because one knows the emptiness of dharmas.' Emptiness and selflessness are simply different perspectives; naming them either way does no harm. Such are their names and meanings.
