Material existence is compared herein to the great ocean of nescience. Another name of this ocean is Vaitarani. In that Vaitarani Ocean, which is the Causal Ocean, there are innumerable universes floating like footballs. On the other side of the ocean is the spiritual world of Vaikuntha, which is described in Bhagavad-gita (8.20) as paras tasmat tu bhavo nyah. Thus there is an ever-existing spiritual nature which is beyond this material nature. Even though all the material universes are annihilated again and again in the Causal Ocean, the Vaikuntha planets, which are spiritual, exist eternally and are not subject to dissolution. The human form of life gives the living entity a chance to cross the ocean of nescience, which is this material universe, and enter into the spiritual sky. Although there are many methods or boats by which one can cross the ocean, the Kumaras recommend that the King take shelter of the lotus feet of the Lord, just as one would take shelter of a good boat. Nondevotees, who do not take shelter of the Lords lotus feet, try to cross the ocean of nescience by other methods (karma, jnana and yoga), but they have a great deal of trouble. Indeed, sometimes they become so busy simply enjoying their troubles that they never cross the ocean. There is no guarantee that the nondevotees will cross the ocean, but even though they manage to cross, they have to undergo severe austerities and penances. On the other hand, anyone who takes to the process of devotional service and has faith that the lotus feet of the Lord are safe boats to cross that ocean is certain to cross very easily and comfortably.
