When sambhrama-prīti becomes firmly fixed, with no doubt that it will decrease, it is called prema. The anubhāvas are such things as complete attachment to the Lord.
Purport
When there is no diminishing of this ecstatic love and when it is freed from all kinds of doubt, the devotee has reached the stage called steady love for Kṛṣṇa. In this stage, all expressions of unhappiness by the devotee are called anubhāva, or ecstatic loving symptoms.

Commentary
When this sambhrama-prīti becomes very fixed (baddha-mūlā) and one is convinced that it can never decrease, it is called prema.
