"The words mṛtyum amṛtam, 'death and immortality,' are significant. In Bhagavad-gītā the Lord says, 'I am ultimate death, who takes away everything from the demons.' The demons' business is to continually struggle for existence as lords over material nature. The demons repeatedly meet death after death and create a network of involvement in the material world. The Lord is death for the demons, but for devotees He is amṛta, eternal life. Devotees who render continuous service to the Lord have already attained immortality, for whatever they are doing in this life they will continue to do in the next. They will simply change their material bodies for spiritual bodies. Unlike the demons, they no longer have to change material bodies. The Lord, therefore, is simultaneously death and immortality. He is death for demons and immortality for devotees. He is the ultimate goal of everyone because He is the cause of all causes."
