The attraction of the gopīs for Kṛṣṇa and the affection of the members of the Yadu dynasty are both accepted as spontaneous, or rāgānugā. The attraction of Kaṁsa to Kṛṣṇa in fear and the attraction of Śiśupāla in envy are not accepted as devotional service, however, because their attitudes are not favorable. Devotional service should be executed only in a favorable frame of mind. Therefore, according to Śrīla Rūpa Gosvāmī, such attractions are not considered to be in devotional service. Again, he analyzes the affection of the Yadus. If it is on the platform of friendship, then it is spontaneous love, but if it is on the platform of regulative principles, then it is not. And only when affection comes to the platform of spontaneous love is it counted in the category of pure devotional service.
There may be some difficulty in understanding that both the gopīs and Kaṁsa achieved the same goal, so this point should be clearly understood, because the attitudes of Kaṁsa and Śiśupāla were different from that of the gopīs. Although in all these cases the focus is on the Supreme Personality of Godhead, and all of the devotees are elevated to the spiritual world, there is still a distinction between these two classes of souls. In the First Canto of Śrīmad-Bhāgavatam it is said that the Absolute Truth is one and that He is manifested as impersonal Brahman, Paramātmā (Supersoul) and Bhagavān (the Supreme Personality of Godhead). Here is a spiritual distinction. Although Brahman, Paramātmā and Bhagavān are the same-and-one Absolute Truth, devotees like Kaṁsa or Śiśupāla could attain only to the Brahman effulgence. They could not have realization of Paramātmā or Bhagavān. That is the distinction.
