True Zen is the realization of the truth of this world, understanding its various causal origins. It lacks the attributes of "without reason" and "eternally unchanging"; it's simply a dynamic, interconnected web of cause and effect. Whatever is gained will eventually be lost, and what is lost never truly belonged to you, even your life will fade away. With such understanding, the truth of this world is emptiness. Why emptiness? Because even your consciousness is not "eternally unchanging." When your mind aligns with emptiness through by Zen Meditation, you attain enlightenment. It’s not about what you get, but it is about you truly know nothing that can be really gotten, then you choose to abide in not clinging. Therefore, Zen Meditation is a tool for realizing the truth of this world, it's rational resolution based on rational thinking. This is the wisdom of the mind.
