🎯 Learning Objectives

1. Describe the circumstances that gave rise to the Diamond Prajna Assembly and understand the truth that Buddhism is inseparable from daily life.
2. Master the two core questions raised by Subhuti: "How should one abide?" and "How should one subdue the mind?"
3. Understand and explain the meaning of the "Four Marks" (self, others, sentient beings, and lifespan) and their obstacles to practice.
4. Comprehend and distinguish between conditioned merit and unconditioned virtue: discern the essential difference in merit between offering all seven treasures across three thousand great thousand worlds and upholding just four lines of verse.
5. Grasp the Prajna logic of "not this, yet named as such": apply this logic to interpret Buddhist concepts, enlightenment stages, pure lands, dust particles, and worlds.

7. Deeply analyze the view of ultimate reality: explain the meaning of "when faith is pure, the true form arises," and comprehend the principle that "to be free from all marks is to be called Buddha."
8. Experience the merit of upholding the sutra: compare the difference in merit between offering one's body and upholding the sutra with unwavering faith, and grasp the deeper motivation behind it.
9. Transform karmic hindrances and self-conception: realize how being ridiculed for upholding the sutra can transform past evil karma, and establish a practice centered on "ultimate non-self."
10. Be able to distinguish the definitions of the "Five Eyes" (flesh eye, heavenly eye, wisdom eye, Dharma eye, Buddha eye) and their hierarchical levels in contemplating one’s true nature.

🔹 Lesson 1: The Prajna Assembly and the Aspiration to Practice

Overview: This course covers the first seven sections of the Diamond Sutra, beginning with the Buddha’s everyday life of "equality and sincerity," leading to the pivotal question posed by Elder Subhuti: "How should one who has generated bodhicitta abide and subdue the mind?" The course delves deeply into the heart of Mahayana Buddhism—cultivating boundless compassion without clinging to the notion of sentient beings, practicing giving without abiding in forms, overcoming attachment to the physical body, and ultimately attaining the liberating state of "no fixed dharma" and "unconditioned dharma."

Learning Outcomes:

• Describe the circumstances that gave rise to the Diamond Prajna Assembly and understand the truth that Buddhism is inseparable from daily life.
• Master the two core questions raised by Subhuti: "How should one abide?" and "How should one subdue the mind?"
• Understand and explain the meaning of the "Four Marks" (self, others, sentient beings, and lifespan) and their obstacles to practice.

🔹 Lesson 2: Practice Beyond Forms and the Merit of Upholding the Sutra

Overview: This lesson focuses on sections eight through thirteen of the Diamond Sutra, exploring the dialectical relationship between "practicing beyond forms" and "the merit of upholding the sutra." It guides learners to understand that true merit lies not in material offerings, but in realizing "unconditioned dharma"; practitioners must release attachment to enlightenment, pure lands, and conceptual labels, achieving the state of "giving rise to the mind without abiding anywhere," and recognizing the supreme value of upholding this sutra.

Learning Outcomes:

• Understand and distinguish between conditioned merit and unconditioned virtue: discern the essential difference in merit between offering all seven treasures across three thousand great thousand worlds and upholding just four lines of verse.
• Master the Prajna logic of "not this, yet named as such": apply this logic to explain Buddhist teachings, enlightenment stages, pure lands, dust particles, and worlds.
• Realize the meditative principles of "non-attainment" and "non-abiding": understand the nature of Subhuti’s attainment and the prophecy bestowed by Buddha Ran Deng, and put them into practice through cultivating a pure mind.

🔹 Lesson 3: Stillness Beyond Forms and Purification of Karmic Obstacles

Overview: This module focuses on the essence of sections fourteen through seventeen of the Diamond Sutra. The core aim is to guide learners in understanding how "letting go of forms" leads to the arising of stillness and ultimate reality; it explores why upholding the sutra surpasses material giving in merit, and explains how practitioners who are ridiculed for upholding the text can purify past karmic debts. Ultimately, it returns to the original aspiration of "ultimate non-self" and the method of subduing the mind.

Learning Outcomes:

• Deeply analyze the view of ultimate reality: explain the meaning of "when faith is pure, the true form arises," and comprehend the principle that "to be free from all marks is to be called Buddha."
• Experience the merit of upholding the sutra: compare the difference in merit between offering one's body and upholding the sutra with unwavering faith, and grasp the deeper motivation behind it.
• Transform karmic obstacles and self-conception: realize how being ridiculed for upholding the sutra can transform past evil karma, and establish a practice centered on "ultimate non-self."

🔹 Lesson 4: Seeing All as One and the Universal Transformation of Dharma

Overview: This course centers on the core teachings of sections eighteen through twenty-two of the Diamond Sutra, exploring the path from perceiving ultimate reality to complete detachment from forms. Topics include the hierarchical levels of the "Five Eyes" and the concept of "three minds cannot be grasped," further analyzing the emptiness of merit, physical form, speech, and Buddhahood, guiding learners to understand the profound truth of "no teaching can be spoken" and "nothing can be attained" — the profound emptiness of reality.

Learning Outcomes:

• Be able to distinguish the definitions of the "Five Eyes" (flesh eye, heavenly eye, wisdom eye, Dharma eye, Buddha eye) and their hierarchical levels in contemplating one’s true nature.
• Understand the principle of "three minds cannot be grasped," and explain its relationship with the eternal true mind and the emptiness of all phenomena.
• Explain why merit, perfect physical form, and the teachings spoken by the Tathagata are all illusory, and grasp the dialectical logic of "because there is no cause, therefore there is no effect."

🔹 Lesson 5: Pure Mind in Good Deeds and the Fullness of Virtue and Wisdom

Overview: This course covers the essence of sections twenty-three through thirty-one of the Diamond Sutra, focusing on teaching practitioners how to cultivate all good deeds with a "non-self" pure mind, and thoroughly understand the profound meanings of "Dharma Body without Form" and "One Harmonious Reality." The course emphasizes that all dharmas are equal and that merit and wisdom are immeasurable, ultimately guiding learners into the liberated state of "no arising of views."

Learning Outcomes:

• Explain the meaning of "all dharmas are equal, without superiority or inferiority," and apply it to daily acts of kindness (giving without form).
• Differentiate between "physical form and appearance" and "pure Dharma Body," and understand the meaning of "if one sees me through form, that person walks the wrong path."
• Elucidate the true meaning of "Thus Come One" (originating nowhere, going nowhere) and the unspeakable nature of "One Harmony."

🔹 Lesson 6: Manifestation Is Not Real and the Diamond Summary

Overview: This final section focuses on the last chapter of the Diamond Sutra, titled "Manifestation Is Not Real, Chapter Thirty-Two." Its core theme contrasts the merit of "material giving" with that of "dharma giving" (upholding and expounding the sutra), and through the famous "Six Like Verses," reveals the illusory nature of all conditioned phenomena. It concludes the entire sutra’s meaning: observing all phenomena with a mind that remains "as it is, unmoving," returning to true nature.

Learning Outcomes:

• Understand the superiority of merit: distinguish the essential difference between worldly merit from "offering seven treasures" and transcendent merit from "upholding and propagating the sutra."
• Master the core contemplative method: realize the essence of "not attaching to forms, remaining as it is, unmoving," and explain the symbolic meaning of the "Six Like" metaphors.
• Summarize the overall meaning of the sutra: understand how to subdue deluded thoughts and abide in the true mind through "unconditioned dharma," completing the practical summary of the Diamond Sutra.
