Brihad Bhagavatamrta
Part 1 Chapter 7 Text 158

gopinam vitatadbhuta-sphutatara-premanalarcis-chata-
dagdhanam kila nama-kirtana-krtat tasam visesat smrteh
tat-tiksna-jvalanocchikhagra-kanika-sparsena sadyo maha-
vaikalyam sa bhajam kadapi na mukhe namani kartum prabhuh

TRANSLATION
The gopis were consumed by the expansive flames of the wondrous blazing fire of love for Krsna. If my guru chants the names of these gopis and recalls a gopi’s distinguishing qualities, he too is touched by sparks shooting forth from the flames of this intense fire, and he at once becomes greatly agitated. Therefore he has to avoid pronouncing the gopis’ names.
