What is our problem?
The problem is that the wave thinks itself separate from the ocean; then there are problems. If a wave thinks itself separate from the ocean, the fear of death will immediately come. The wave has to die and the wave can see all around dying waves. And you cannot deceive yourself for long. The wave is seeing that other waves are dying, and the wave knows that even in its rising, death is hidden somewhere, because those other waves a moment before were rising and now they are falling down, dispersing. So you are to die.
If the wave thinks itself separate from the ocean the fear of death is bound to appear sooner or later. But if the wave knows that it is not and only the ocean is, there is no fear of death. Only a wave can die, not the ocean. I can die, but not life. You can die, you will die – but not the cosmos, not the existence. The existence goes on waving. It has waved in you, it will wave in others. And while your wave may be disappearing, just by your dispersal other waves will arise and the ocean continues.
Once you detach yourself from the wave form, and you become one and feel one and realize oneness with the ocean, the formless, there is no death for you.
