Erotic chat line? Hey, if you think attraction for Krishna, even of the sringara nature, is something that can be compared to mundane eroticism, you got another think comin' buddy!
Do you think when we sing "Madhuraashtakam" where we are even saying "His lips are sweet," do you think that is something for an "erotic chat line?" No! That is a fitting description for Krishna, but if you don't understand or it seems like mundane eroticism, then please just ignore. If it bothers you, then just don't think of it. Ok?
