The ocean of nescience is very difficult to cross because it is infested with many dangerous sharks. Although those who are nondevotees undergo severe austerities and penances to cross that ocean, we recommend that you simply take shelter of the lotus feet of the Lord, which are like boats for crossing the ocean. Although the ocean is difficult to cross, by taking shelter of His lotus feet you will overcome all dangers.
