大方廣佛華嚴經疏 49.12

49.12

Second is the simile of empty space being without discrimination, illustrating the body free from attachment and obstruction; hence the sūtra concludes, "His deeds are unobstructed, like empty space." Because empty space is without discrimination, it does not obstruct the manifestation of forms. Because wisdom is without discrimination, it does not obstruct benefiting sentient beings.
