According to this YouTUBE video, Lord Krishna appears to Devaki and Vasudeva in Evil Kansa's prison.
Lord Krishna visits Devaki and Vasudeva in Evil Kansa's Prison
Lord Krishna tells Devaki how to get salvation, but Devaki says she doesn't wish for salvation. Instead, she wishes to have mother-son relationship with Lord Krishna (who is really incarnation of Lord Vishnu).
According to Scriptures, why would anyone want to forgo salvation? This is new to me.
