Bhaktivedanta Narayana Gosvami
From the book “Sri Vraja-maṇḍala-parikramā”:
Mahārānī Yamunā has the same darkish blue complexion as Kṛṣṇa. She assists in the playful amorous pastimes of Śrī Rādhā-Kṛṣṇa Yugala in every respect, and flows on three sides of Vṛndāvana. To fully support the rasa-vilāsa of Priyā-Priyatama, she creates countless charming nikuñjas on both her banks with various kinds of dense trees and creepers laden with flowers and fruits.
She is ornamented and beautified with divine ghāṭas bedecked with jewels, and with various bowers made from kadamba, tamāla, āmra, bakula and other types of trees. The Divine Couple Śrī Rādhā-Kṛṣṇa perform water pastimes and boating pastimes with the sakhīs in the waters of Śrī Yamunā. This water is saturated with prema and is always decorated with seven-petalled lotuses. This Bhagavatī Yamunā, who serves the Youthful Couple eternally, is supremely worshipful.
In Caitanya-candrodaya-nāṭaka (5.35) Śrīla Kavi-karṇapura glorifies Śrī Yamunā-devī as follows (also quoted in Śrī Caitanya- caritāmṛta, Madhya-līlā 3.28):
para-prema-pātrī drava-brahma-gātrī
aghānāṁ lavitrī jagat-kṣema-dhātrī
pavitrī-kriyān no vapur-mitra-putrī
goloka-saukhya-rasa-pūramahiṁ mahimnā
āplāvitākhila-sudhāsu-jalāṁ sukhābdhau
rādhā-mukunda-muditāṁ yamunāṁ namāmi
