Sri Caitanya-caritamrta

CC Madhya-lila

When the permanent ecstasies [neutrality, servitorship and so on] are mixed with other ingredients, devotional service in love of Godhead is transformed and becomes composed of transcendental mellows.

CC Madhya 23.47, Translation and Purport

When the permanent ecstasies [neutrality, servitorship and so on] are mixed with other ingredients, devotional service in love of Godhead is transformed and becomes composed of transcendental mellows.

In the Bhakti-rasāmṛta-sindhu (2.1.4-5), the following definition is given:

athāsyāḥ keśava-rater lakṣitāyā nigadyate

sāmagrī-paripoṣeṇa paramā rasa-rūpatā

vibhāvair anubhāvaiś ca sāttvikair vyabhicāribhiḥ

svādyatvaṁ hṛdi bhaktānām ānītā śravaṇādibhiḥ

eṣā kṛṣṇa-ratiḥ sthāyī bhāvo bhakti-raso bhavet

“Love for Kṛṣṇa, Keśava, as previously described, reaches the supreme state of being composed of mellows when its ingredients are fulfilled. By means of vibhāva, anubhāva, sāttvika and vyabhicārī, hearing and chanting are activated, and the devotee is able to taste love for Kṛṣṇa. Then attachment for Kṛṣṇa, or permanent ecstasy (sthāyi-bhāva), becomes the mellow of devotional service (bhakti-rasa).”
