This is what might be explained by shiva today.
First try to understand what a wave is, and then you can feel how this consciousness of waves can help you to enter into meditation. You see waves in the ocean. They appear; they are in a sense, and still in a deeper sense they are not. This is the first thing to be understood about a wave. The wave appears; it is there in a sense, but still it is not there in a deeper sense. In a deeper sense only the ocean is. You cannot have a wave without the ocean, and even while the wave is there, only the ocean is. The wave is just a form, not a substance. The ocean is substantial; the wave is just a form.
Because of language many problems are created. Because we say "wave," it looks as if a wave is some thing. It would be better if we use not wave, but "waving." There is no wave, just waving -- just an activity, not a thing; just a movement, not a substance; just a process, not matter. The matter is the ocean; the wave is just a form. The ocean can be silent. The waves will disappear, but the ocean will be there.
The ocean can be silent or in movement or in much activity or in no activity, but you cannot find a silent wave. A wave is activity, not a substance. When the activity is there, the wave is there: it is a waving, a movement -- a simple form of movement. But when the silence comes, when inactivity comes, the wave is no more and the ocean is there. In both the cases the ocean is the reality. The wave is just a play-form. The wave happens and disappears, the ocean remains.
Secondly, waves appear as individuals. Each wave has its own personality -- unique, different from any other. No two waves are similar. Some waves are big, some waves are small. They have their own peculiar characteristics. Each wave has its own character, and, of course, each wave is different from the other. One wave may rise, another may die. While one is rising, another is dying. Both cannot be the same because one is rising, another is dying. Still, the reality behind both is the same. They look different, they look separate, they look individual, but the look is fallacious. Deep down only one ocean is, and no matter how they look unrelated they are related. And while one wave is rising and another is dying, you may not see any relationship;
