Testing the Heart Amidst Power: A Lesson on the Qualities of a Sage

The candlelight flickered in the private chamber of Hung Dao Vuong Tran Quoc Tuan, casting long, dark shadows against the cold stone walls. Outside, the night was deep, and the wind howling through the mountain passes sounded like the sighs of history itself. On the table lay a vast military map, yet the eyes of the Supreme Commander of Dai Viet did not look upon it. He gazed into an infinite void, where the memory of his late father, An Sinh Vuong Tran Lieu, still haunted him.

Years ago, as Tran Lieu lay dying, he had gripped his son’s hand tightly. His voice trembled but was filled with fierce determination. He spoke of injustice, claiming that their elder branch should have held the throne, but Tran Thu Do had forced the younger branch, led by Tran Canh, to ascend instead. He urged his son to remember this grievance and to seize the opportunity to reclaim the crown for their lineage when the time came.

Those words were etched deeply into Tran Quoc Tuan’s mind. Now, that opportunity had arrived. He held absolute military power, leading the army with the reverence of the court and the people. With just a nod or a small order, he could overthrow the king and take the world without resistance. Power lay within reach, sweeter and more enchanting than any victory on the battlefield.

Tran Quoc Tuan summoned his sons. His gaze was sharp, probing each face. He asked directly about his father’s wish to reclaim the throne, noting that with his current authority, such a task would be effortless. He sought to know what they thought. The older sons bowed their heads in silence or shook them gently, expressing loyalty to the king and the nation. However, his eyes settled on his youngest son, Tran Quoc Tang. Ambitious and seeing a once-in-a-lifetime chance, Tang stepped forward eagerly, urging immediate action before the moment slipped away.

The atmosphere in the room froze instantly. Tran Quoc Tuan’s heart clenched, not from fear, but from the pain of seeing flesh and blood blinded by the desire for power. He stood up, majestic yet heavy with sorrow. After a pause, he ordered his guards to take Quoc Tang outside and execute him. The young man’s screams mixed with the night wind. The guards, stunned but disciplined, obeyed. Just before the blade touched his neck, Tran Quoc Tuan raised his hand to stop them. With red-rimmed eyes, he looked at his trembling son kneeling at his feet.

He explained that he had tested their hearts to affirm his own stance. He would never betray the country nor cause chaos for personal revenge. From that day forward, he despised Tang for choosing power over righteousness. Later, Tran Quoc Tuan invited Grand Tutor Tran Quang Khai, who belonged to the younger branch and had historical tensions with the elder one, to his residence. In a private bath, Tran Quoc Tuan personally poured water over Tran Quang Khai. This rare gesture symbolized absolute reconciliation and unity between the two royal factions, dispelling all suspicion and unifying the nation’s will against the Mongol invaders.

Through his selfless devotion to the country and his rejection of personal power for the greater good, Tran Quoc Tuan led the people of Dai Viet to defeat three invasions by the most powerful empire of that era. While these victories were great, it was his radiant moral character that earned him the title of "Saint" among later generations.

According to Venerable Thich Chan Quang, to be called a "sage" in the eyes of the nation requires more than just great achievements, such as defeating enemies. It demands transcendent moral qualities. The story of Tran Hung Dao proves that when faced with the opportunity to do wrong, such as seizing the throne or seeking revenge, restraining one’s desires and placing national interest and ethics above all else represents the pinnacle of human character. Ordinary beings are often controlled by power and wealth, but sages rise above such temptations, maintaining a pure and wholesome mind.
