The answer is YES!
But it is also true that the specific word manjari or the phrase “manjari bhava” IS NOT FOUND in Chaitanya Caritamrta, Bhakti Rasamrita Sindhu, Brhad-bhagavatamrita, or the Srimad Bhagavatam.
Why manjari bhava is not directly mentioned in Chaitanya Caritamrita? Early during his stay at Radha-kunda, Sri Krishna Dasa Kaviraja wrote Govinda-lilamrita in Sanskrit, which is full of manjari names and sevas.
Then at the end of his life at Radha-kunda, he summarized all the Goswami’s books and teachings (all written in Sanskrit) in simple Bengali language so the masses of Gaudiya Vaisnavas, mostly Bengalis at that time, could easily understand the basic tenets of Gaudiya Vaisnava philosophy.
Since manjari bhava is a confidential aspect of Mahaprabhu’s teachings, Sri Krishna Dasa Kaviraja did not deem it fit for mass distribution. Thus he did not directly mention the words manjari or manjari bhava. But he did not avoid or overlook it either. Throughout the Chaitanya Caritamrta, Sri Krishna Dasa Kaviraja mentions terms like “gopi-bhava” “smarana” “siddha-deha” “cinte” (meditate) which are all directly related to manjari and manjari bhava.
Nevertheless, the practice of raganuga bhakti sadhana and gopi-bhava is integral to the teachings of Sri Chaitanya Mahaprabhu. Thus, the word and phrase MANJARI and MANJARI BHAVA, along with the meaning and the practice of worshiping Radha-Krishna in madhura-rati as a sakhi maidservant, dasi (aka manjari, kinkari) of Sri Radha in manjari-bhava, IS MENTIONED and specifically described in the following important books of our Gaudiya Vaisnava Goswamis and Purvacharyas
