華嚴經探玄記 15.83

15.83

第三眼相亦一，釋中初所見無礙故名自在、後眼光現佛亦名自在雲。《智論》真眼相，如好青蓮花，又如牛王，眼睫長好不亂。

The third mark of the eyes is also one. In the explanation, first, that which is seen is unhindered, hence named 'sovereign'; later, the light of the eyes manifests Buddhas, also named 'sovereign cloud'. The Dà zhìdù lùn states that the mark of the true eyes is like a fine blue lotus, or like the king of oxen, with eyelashes long, fine, and unkempt.
