楞伽阿跋多羅寶經註解 1.247

1.247

自此至毛孔眉毛幾，皆佛反詰大慧所問。不周量者，度數也。上中下眾生，總十界而言也。身幾塵，謂身量長短輕重也。

From here down to 'how many pores and eyebrows', all are the Buddha's counter-questions regarding Mahāmati's inquiries. 'Measurements' refers to degrees and quantities. 'Superior, middling, and inferior sentient beings' speaks collectively of the ten realms. 'Of how many particles is the body' refers to the length, lightness, and weight of the body's measure.
