Bodha-bhit means the particular bodha arising from destruction of ignorance. These are said to be causes of rati (rati-vibhāvatā) “somewhat.” It should be understood from this that rati and these vyabhicāri-bhāvas mutually act upon each other. They are said to be a cause of rati because they cause further appreciation of Kṛṣṇa (they stimulate rati, but rati is permanent and not caused).
