Vaishnava summer festival – BALTIC 2017 (Album with photos)
Srila Prabhupada: If a person does not cry or exhibit bodily changes after chanting Hare Krishna without offense, it is to be understood that he is hardhearted and that therefore his heart does not change even after he chants the holy name of God. These bodily changes can take place due to ecstasy when we offenselessly chant the holy names of God. (Srimad-Bhagavatam, 3.15.25 Purport)
