In Śrī Rādhā-kṛṣṇa-gaṇoddeśa-dīpikā by Śrīla Rūpa Gosvāmī, under the division entitled “Sri Krsna’s Beloveds (sri krsnasya preyasyah), there is a section “Śrīmatī Rādhikā’s mañjarīs (śrī-rādhāyā mañjaryaḥ)” and a separate section “Śrī Rādhā’s maidservants (śrī-rādhā-bhṛtyāḥ).” For example, the table of contents has the following two sections:
• Śrīmatī Rādhikā’s mañjarīs (śrī-rādhāyā mañjaryaḥ)
• Śrī Rādhā’s maidservants (śrī-rādhā-bhṛtyāḥ)
The Sanskrit word used for maidservants is bhṛtyāḥ. In the last verse quoted below, you will see some priya-narma sakhās listed as Rādhā’s maidservants. In the Hindi edition, the phrase “maidservants and servants” is not used because “maidservants” covers both genders.
The word "maidservants" is used for priya-narma sakhās because they have both sakhā mood and mañjarī mood . For them, sakhā mood is their sthāyibhāva and mañjarī mood is sañcāri-bhāva. One is aṅgi and one is aṅga.
“The priyanarma-sakhās are superior in every way to the three other types of sakhās. They are engaged in extremely confidential services and are possessed of a very special bhāva (sakhī-bhāva).” Excerpt From: Śrī Śrīmad Bhaktivedānta Nārāyaṇa Gosvāmī Mahārāja. “Śrī Bhakti-rasāmṛta-sindhu-bindu.” Gaudiya Vedanta Publications. iBooks.
When Śrī Śrīmad Bhaktivedānta Nārāyaṇa Gosvāmī Mahārāja says that Srila Bhaktivedānta Swāmī Mahārāja is a maidservant, he is speaking vaiṣṇava siddhānta. We have guru-nistha in his words. He never says Swāmī Mahārāja is a mañjarī. He only says maidservant and priya-narma sakhas are in category of bhṛtyāḥ as delineated by Śrīla Rūpa Gosvāmī himself.
