Some philosophers have, purely on the basis of the empirical perspective, explored the truth of matter. Some have explored the truth of matter in terms of the transcendental perspective.
Thus there are two strains of thought: one which follows the perspective of dravyarthik naya or the substantial perspective and the other which follows the paryayarthik naya or the modal perspective.
One, a perspective, that explains and explores the wave theory and the other, a perspective that explains and explores the unfathomable ocean beneath the waves. The two cannot be divided. We see the network of waves before our eyes. When there are many waves in the ocean, then only are they visible. The ocean is hidden below them. Those who saw only the waves of the ocean gave explanations of the modes and their results.
They said that the whole world was changing, that it was being recreated. Those who saw that this change was not real and that the truth is that which is hidden below the change were able to grasp the root substance and explained that.
They categorized the waves as unreal, as untruth. Waves were thus left out. Both perspectives got divided, became uni-dimensional. The whole truth was not comprehended.
