Unalloyed devotion means service to the Lord without desire for the personal benefits. And the powerful Personality of Godhead Sri Krsna can be fully satisfied by such unalloyed devotees free from all sorts of desires for personal benefit. Unalloyed devotional service of the Lord progresses in different stages.
Practice of devotional service in the material field is of eighty-one different qualities, and above such activities there is the transcendental practice of devotional service, which is one and is called sadhana-bhakti. When unalloyed practice of sadhana-bhakti is matured into transcendental love for the Lord, the transcendental loving service of the Lord begins gradually developing into nine progressive stages of loving service under the headings of attachment, love, affection, feelings, affinity, adherence, following, ecstasy and intense feelings of separation.
The attachment of an inactive devotee develops up to the stage of transcendental love of God. Attachment of an active servitor develops up to the stage of adherence, and that for a friendly devotee develops up to the stage of following, and the same is also the case for the paternal devotees. Devotees in conjugal love develop ecstasy up to the stage of intense feelings of separation. These are some of the features of unalloyed devotional service of the Lord. SB 1.7.10
