Jāhnavā Ṭhākurāṇī - Śrī Anāṅga Mañjarī about bhāvollāsa

Jāhnavā Ṭhākurāṇī - Anāṅga Mañjarī
जाह्नवा ठाकुराणी -  अनांग मञ्जरी
and bhāvollāsa - भावोल्लास

In the Muralī-vilāsa ("The pastimes of the Flute"), Jāhnavā Ṭhākurāṇī supplies some answers in regarding to bhāvollāsa in a conversation with her adopted son and disciple, Rāmāi Ṭhākur (Rāmacandra Bābāji):

Rāmāi Ṭhākur said, "Please continue. Tell me about this attitude called bhāvollāsa. Where is it to be found?"

Mother Jāhnavā answered, "Dear one, listen carefully. This bhāvollāsa-rati can only be found in the holy land of Vrindavan. The Lord's abode of Vrindavan is even beyond the reach of the gods. There, the very youthful Divine Couple reigns supreme. Serving them rhapsodically day and night are handmaidens like Śrī Rūpa Mañjarī and Śrī Anaṅga Mañjarī who possess this bhāvollāsā rati. The happiness of the Divine Couple is their happiness; they know nothing else.

Always immersed in an ocean of bliss in the service of Rādhā and Kṛṣṇa, they are oblivious to time. Their love, which delights in feeling, like a companion mood, aims at giving pleasure to Kṛṣṇa; it feeds and nourishes the love between Rādhā and Kṛṣṇa.

They are all identical with Śrīmatī Rādhārāṇī; they merely possess different bodies-one life, one soul, they all are expansions of Rādhā. When she and her lover are at the height of rapturous intimacy and the hair stands erect on her body, the very same phenomenon occurs on the bodies of her girlfriends. They experience seven times the pleasure that Rādhā does!

Sometimes, on some pretext, she arranges for them to have trysts with Kṛṣṇa, seeing which her happiness increases thousands of times.
This is a description of the bhāvollāsa love, which caused the Lord to say in the circle dance,'
I am unable to repay you gopīs for the love you have shown me.'"Muralī-vilāsa, ch. 6, p. 46.
