Srimad Bhagavatam

References to text SB 11.2.40
SB 11.2.40: By chanting the holy name of the Supreme Lord, one comes to the stage of love of Godhead. Then the devotee is fixed in his vow as an eternal servant of the Lord, and he gradually becomes very much attached to a particular name and form of the Supreme Personality of Godhead. As his heart melts with ecstatic love, he laughs very loudly or cries or shouts. Sometimes he sings and dances like a madman, for he is indifferent to public opinion.

Our master, the Personality of Godhead Nārāyaṇa, who alone rules the three worlds, whom one can serve in meditation, and who happily shares His personal domain, is manifest before us. Yet still we beg for the service of some minor lord of a few villages, some lowly man who can only meagerly reward us. Alas, what foolish wretches we are!

My mind cannot turn from Śrī Kṛṣṇa''s lotus feet, even for a moment. So let my dear ones and other relatives criticize me, my superiors accept or reject me as they like, the common people spread evil gossip about me, and my family''s reputation be sullied. For a madman like me, it is honor enough to feel this flood of love of Godhead, which brings such sweet emotions of attraction for my Lord.
Mukunda-mala-stotra
MM 42
One who understands perfectly the process of devotional service in love of Godhead becomes intoxicated in its discharge. Sometimes he becomes stunned in ecstasy and thus enjoys his whole self, being engaged in the service of the Supreme Self.
