There is the following statement by a gopī: "My dear Kṛṣṇa, the first thing You should do is just embrace me with Your strong arms. Then, my dear friend, I shall first smell Your head, and then I shall enjoy with You." This is an example of incompatibility in which conjugal love is the whole and servitorship is the part.
One devotee said, "My dear Kṛṣṇa, how can I address You as my son when You are addressed by the great Vedāntists as the absolute truth and by the Vaiṣṇavas who follow the principles of Nārada-pañcarātra as the Supreme Personality of Godhead? You are the same Supreme Person, so how shall my tongue be so extraordinarily bold as to address You as an ordinary son?" In this statement there is a mixture of neutrality and parental love, and the result is incompatible.
Another devotee said, "My dear friend, my youthful beauty is as temporary as lightning in the sky, and therefore, my possessing attractive bodily features is unimportant. I have never met Kṛṣṇa, so I request you to please arrange for my meeting Him immediately." In this statement there is the incompatibility of a neutral mellow mixed with conjugal love.
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.
In the Vidagdha-mādhava, second act, verse 29, Paurṇamāsī tells Nāndīmukhī: "Just see how wonderful it is! Great sages meditate upon Kṛṣṇa after being relieved from all material transactions, and with great difficulty they try to situate Kṛṣṇa in their hearts. And opposed to this, this young girl is trying to withdraw her mind from Kṛṣṇa so she can apply it in the material activities of sense gratification. What a regrettable thing it is that this girl is trying to drive away from her heart the same Kṛṣṇa who is sought after by great sages through severe austerities and perseverance!" Although in this statement there are contradictory mellows of ecstatic devotion, the result is not incompatible because conjugal love is so elevated that it is defeating all other varieties of mellows. Śrīla Jīva Gosvāmī comments in this connection that such a loving state of mind is not possible for all. It is only possible in the case of the gopīs of Vṛndāvana. There are many other instances of contradictory mellows where there is no perverted experience of rasābhāsa.
