Ecstatic love of Godhead can be potently invoked simply by following the rules and regulations of devotional service as they are prescribed in scriptures, under the direction of a bona fide spiritual master. In the Eleventh Canto, Second Chapter, verse 40, of Śrīmad-Bhāgavatam, this ecstatic love, born of the execution of regulative devotional service, is explained: "A devotee, in the course of executing the regulative principles of devotional service, develops his natural Kṛṣṇa consciousness, and being thus softened at heart he chants and dances like a madman. While performing chanting of the holy name of the Lord, he sometimes cries, sometimes talks wildly, sometimes sings and sometimes—without caring for any outsider—dances like a madman."
In the Padma Purāṇa there is a statement about ecstatic love born of spontaneous affection. Candrakānti, a celebrated fair-faced girl, rigidly observed celibacy in order to obtain Kṛṣṇa as her husband. She always engaged herself in meditating on the transcendental form of the Lord and always chanted the glories of the Lord. She did not desire to accept anyone else as her husband. She had firmly decided that only Lord Kṛṣṇa would be her husband.
