大方廣佛華嚴經疏 5.3

5.3

第二集因，亦有十因：一曾與毘盧遮那如來同集善根故、二蒙佛四攝曾攝受故、三往在生死聞圓法故、四曾發大心護一切故、五往發大願願事佛故、六隨逐如來無厭足故、七樂聞正法心無倦故、八善能散滅我慢心故、九福智已淨身周遍故、十同一法性善根大海之所生故。為此多義，得預斯會。中有集因亦通集意，及隨諸眾各有別因，可以思準。

Second, the causes of gathering also have ten causes: 1. Because they formerly gathered roots of goodness together with Vairocana Tathāgata. 2. Because they were formerly embraced by the Buddha's four means of embrace. 3. Because in the past, while in saṃsāra, they heard the complete Dharma. 4. Because they formerly generated the great mind [of bodhi] to protect all. 5. Because they formerly made great vows wishing to serve the Buddha. 6. Because they follow the Tathāgata without satiety. 7. Because they delight in hearing the true Dharma without mental weariness. 8. Because they are skilled at dissipating and destroying the mind of arrogance. 9. Because their merit and wisdom are already purified and their bodies are all-pervading. 10. Because they are born from the great ocean of roots of goodness of the identical dharmatā. For these many reasons, they are able to participate in this assembly. Among these, the causes of gathering also apply to the intention of gathering, and each assembly has its specific causes as appropriate, which can be deduced by reflection.
