BG Chap 12 - The devotee who is most dear to Kṛṣṇa

The devotees who completely take up the nectarean path full of good qualities which has just been taught, who are full of faith in that method, and who become completely absorbed in Kṛṣṇa are most dear to Him. The Lord says this is the result of hearing and considering the qualities by persons desirous of completely obtaining all those qualities. These qualities, which arise from sense control, which in turn arises from bhakti, are not material qualities. Kṛṣṇa is pleased by bhakti, not by good qualities. The devotees described up to this point were fixed in their individual natures with certain qualities. But those who desire all of the qualities of all the types of devotees are superior to those who have attained some of the qualities. Therefore, even during the stage of sādhana, they are superior to those on other paths even if the others have achieved the perfected stage of their paths. For this reason, Kṛṣṇa uses the term ‘atīva’ (extremely) here to describe such devotees.
