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 in search after happiness, recommendation is that we simply take shelter of the lotus feet of the Lord, by congregational chanting and dancing Holy Name with pure lives.
Lotus feet of the Lord are like boats for crossing the ocean. Although the ocean is difficult to cross, by taking shelter of His lotus feet and by helping others to get on board – it is possible to overcome all dangers.
