These transcendental symptoms are described in Śrīmad-Bhāgavatam (11.3.31):
- smarantaḥ smārayantaś ca
- mitho 'ghaugha-haraṁ harim
- bhaktyā samjātayā bhaktyā
- bibhraty utpulakāṁ tanum
"When devotees discuss subjects dealing with the Supreme Lord, who can cleanse the heart of His devotee from all kinds of sinful reactions, they become overwhelmed with ecstasy and display different symptoms due to their devotional service."
