A lusty woman in Kailāsa once told Kṛṣṇa, "My dear Kṛṣṇa, may You have a long life!" Then, after saying this, she embraced Kṛṣṇa. This is an example of incompatibility resulting from a mixture of parental love and conjugal love.
The purpose of the above analysis is to show that in the mixture of various mellows, or reciprocations of ecstatic love between Kṛṣṇa and the devotees, if the result is not pure there will be incompatibility. According to the opinion of stalwart devotees like Rūpa Gosvāmī, as soon as there are contradictory feelings, the result is incompatible.
Once an ordinary female devotee addressed Kṛṣṇa, "My dear boy, I know that my body is just a composition of flesh and blood and can never be enjoyable to You. But still, I have been so attracted by Your beauty that I wish that You accept me as Your conjugal lover." In this statement there is incompatibility caused by a mixture of ghastliness and conjugal love in devotional service.
Śrīla Rūpa Gosvāmī warns devotees to not commit such incompatibilities in their writings or in their dealings. The presence of such contradictory feelings is called rasābhāsa. When there is rasābhāsa in any book of Kṛṣṇa consciousness, no learned scholar or devotee will accept it.
