Zen is the Worldview, Code is the Method 禅是世界观，代码是方法论

Long-running reflections from this homepage — classical Buddhist concepts, re-expressed in the language of programmers. 以下哲思源自本主页的长期思考——以程序员的语言，重新诠释佛学中的经典概念。

Heart Sutra · OOP

Emptiness is an Abstract Class · 空即是色，色即是空「空」是抽象类 · 空即是色，色即是空

Emptiness is an abstract class, Form a concrete class, Appearance an instance. You see a cat: this specific cat is the instance, "cat" is the abstract class, "black cat" the concrete class — the mind moves from concrete to abstract: a verifiable cognitive path. 空（Emptiness）是 abstract class，色（Form）是 concrete class，相（Appearance）是 instance。你看见一只猫：眼前这只具体的猫是实例，「猫」是抽象类，「黑猫」是具体类——心智从具体走向抽象，这是一条可验证的认知路径。

Emptiness : Form : Appearance = abstract class : concrete class : instance

Four No-Selves · Diamond Sutra

"I" Cannot Be Instantiated · My Nature is an Abstract Class 「我」无法被实例化 · My Nature is an Abstract Class

"I" is fundamentally an abstract class: cannot use "this" → no self; cannot instantiate → no person; cannot inherit → no sentient beings; no lifecycle methods → no lifespan. The end of the four lines is an object that can never be new-ed. 「我」在本质上是一个抽象类：不能使用 this → 无我；不能实例化 → 无人；不能继承 → 无众生；没有生命周期方法 → 无寿者。四句偈的尽头，是一个永远无法 new 出来的对象。

no this · no instantiate · no inherit · no lifecycle

Worldview · Pattern

The World is a Running Instance · The World 世界是一个运行中的实例 · The World

The universe is a running virtual system (instance). A class can define many worlds, yet our universe-instance is unique; a cloned object is always a new object. "I" is an object implementing the State Pattern — behavior changes with internal state. 宇宙是一个正在运行的虚拟系统（instance）。类（class）可以定义许多世界，而我们的宇宙实例独一无二；克隆出的对象，永远是新的对象。「我」是一个实现 State Pattern 的对象——随内部状态而改变行为。

universe = a running instance of class World

Epistemology · Testing

Only Outside the System Can You Test It · The Predict Principle 在系统之外，才能测试系统 · The Predict Principle

With the underlying SDK you could debug this world. Parameters are pseudo-random: identical input always yields identical output. Valid testing must happen outside the system — inside it, test data, execution and observation cannot be cleanly separated. 拿到底层 SDK，就能调试这个世界。参数是伪随机的：相同输入，必然得到相同输出。而有效的测试必须在系统之外进行——系统之内，测试数据、系统执行与观测结果，无法被干净地分离。

identical input yields identical output

Thought Experiment · Game

Are We NPCs or Players? · Virtual Game 我们是 NPC，还是玩家？ · Virtual Game

Within this world-instance we generally behave like NPCs. External "players" may exist, but their presence could appear in diverse, indirect forms — not limited to simple control. The question itself is the best breakpoint. 在这个世界实例中，我们通常表现得像 NPC。外部的「玩家」可能存在，但他们的出现形式或许多样而间接——未必只是简单的操控。这个问题本身，就是最好的调试断点。

NPC or Player — that is the question

No Ego · Einstein

More Knowledge, Less Ego · No Ego 知识越多，我执越少 · No Ego

Ego = 1 / Knowledge. Einstein quotes long kept on this homepage: "More the knowledge, lesser the ego; lesser the knowledge, more the ego." "We should take care not to make the intellect our god — it has powerful muscles, but no personality." Ego = 1 / Knowledge。主页长期引用的爱因斯坦语录：「知识越多，我执越少；知识越少，我执越多。」「当心别把理智奉若神明——它虽肌肉强健，却没有个性。」

More the knowledge, lesser the ego

import math

class Supreme_Wisdom:
    knowledge = math.inf

    def __init__(self):
        print("All things being equal = Everything happens as expected")

    def ego(self):
        return 1 / self.knowledge

    def power(self):
        return self.knowledge

    def personality(self):
        return 1 / self.power()

    def being(self):
        return 1 / self.knowledge

    def time_frame(self):
        return float(self.knowledge)

    def life(self):
        return 1 / self.time_frame()

📜 Divination Poem · 2021/07/20 📜 预测回收台湾签诗 · 2021/07/20 — 欲进又徘徊，心危事不危。
水边人指引，名利得荣归。

I wished to move forward but hesitated. The heart sensed danger, yet all was actually well.
Guided by one who lives by the water, fame and fortune return in honor.

Of the same origin as "seeing one's true nature" — a record of understanding the abstract "I": Consciousness: understanding the abstract "I" and nothing else. 与「明心见性」同源——记录对抽象之「我」的理解：Consciousness: understanding the abstract "I" and nothing else.
