Bhakti-rasāmṛta-sindhu .1.42
Blended reading (Sanskrit + English inline)
This fact is corroborated by Kṛṣṇa in the Eleventh Canto of Śrīmad-Bhāgavatam, Fourteenth Chapter, verse 20, where He says, “My dear Uddhava, you may know it from Me that the attraction I feel for devotional service rendered by My devotees is not to be attained even by the performance of mystic yoga, philosophical speculation, ritualistic sacrifices, the study of Vedānta, the practice of severe austerities or the giving of everything in charity. These are, of course, very nice activities, but they are not as attractive to Me as the transcendental loving service rendered by My devotees.”
…Na sadhayati means “those processes are not means of attaining Me.” Ūrjitā means “very strong and intense, because of not being covered by jñāna or karma.”
Though one may conclude that the bhakti mentioned here is sādhana by comparing it with other processes such as sāṅkhya, it cannot be an example of sādhana that brings Kṛṣṇa under control, because of the statement in verse 41 that Kṛṣṇa is brought under control only by sādhya-bhakti. Thus, the meaning is “bhakti, after producing sādhya-bhakti (prema) controls Me.”
