大乘百法明門論開宗義決 1.124

1.124

Regarding 'Because of this, the Tathāgata's eighth pure consciousness carries only old seeds,' and so forth: since wholesome and defiled [dharmas] are excluded from being perfumed, and the Buddha's eighth consciousness is exclusively wholesome and therefore not perfumed, an objection arises: 'If it is neither what is perfumed nor what can perfume, then the Buddha-fruition should lack seeds; how could it give rise to all wholesome qualities?' To resolve this objection, it is said: 'The pure consciousness carries only old seeds; it does not receive new perfuming.'
