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.
