CC Antya 20.147
mora vāṇī — śiṣyā, tāre bahuta nācāi
The mercy of their lotus feet is my spiritual master, and my words are my disciples, whom I have made dance in various ways.
Upādhyāyī, or upādhyāya, refers to one who teaches when approached (upetya adhīyate asmāt). In the Manu-saṁhitā it is said:
yo ’dhyāpayati vṛtty-artham upādhyāyaḥ sa ucyate
“One who teaches others a part of the Vedas or literatures supplementary to the Vedas may be called upādhyāya.” Upādhyāya also refers to one who teaches art.
