Reverential devotion for the Lord gradually increases and transforms itself into ecstatic love, then affection and then attachment. In the Tenth Canto of Śrīmad-Bhāgavatam, Thirty-eighth Chapter, verse 6, Akrūra says, "Because I am going to see Lord Kṛṣṇa today, all symptoms of inauspiciousness have already been killed. My life is now successful, because I shall be able to offer my respects unto the lotus feet of the Supreme Personality of Godhead!"
Another devotee in ecstatic reverential affection once said, "When will that glorious day in my life come when it will be possible for me to go to the bank of the Yamunā and see Lord Śrī Kṛṣṇa playing there as a cowherd boy?"
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.
The symptom of ecstatic affection with reverence felt by Bali Mahārāja was expressed as follows: "My dear Lord, You have simultaneously punished me and showed me Your causeless mercy. My conclusion is that when I have taken shelter of Your lotus feet I shall never be disturbed in any condition of life. Whether You give me the opportunity to enjoy all the yogic perfections or You put me into the most abominable condition of hellish life, I shall never be disturbed."
