Can the following verse from the Kumāra-sambhavaṃ  be taken as having an oblique reference to rubrication? [Unless we take the second pāda to be a qualifier for the rikta version of the bhūrja-patra]

nyastākṣarā dhātu-rasena yatra bhūrja-tvacah kunjara-bindu-śoṇāḥ |

vrajanti vidyādhara-sundarīṇam'ananga-lekha-kriyayo'payogam ||  1.7 ||
