Why did the Jade Emperor summon the Buddha instead of the Three Pure Ones to subdue Wukong?

During Sun Wukong’s havoc in the Heavenly Palace, why did the Jade Emperor summon the Buddha (Tathagata) instead of the Three Pure Ones?

A superficial, direct reason was that Laozi (one of the Three Pure Ones) had just suffered a humiliating setback. His Eight Trigram Furnace failed to kill Sun Wukong and instead fueled the monkey’s arrogance. Worse still, Laozi’s performance was so poor that the celestial beings doubted it reflected his true power. Consequently, many heavenly soldiers and generals inferred Laozi’s lenient stance toward the monkey and turned a blind eye to Wukong whenever possible.

Moreover, the Three Pure Ones transcend mundane conflicts. They serve as spiritual leaders, not part of the administrative or military systems of heaven.

Though the Jade Emperor ruled the Heavenly Court, facing Primordial Deities like the Three Pure Ones required tact, summoning Tathagata Buddha, a representative of an external power, allowed him to assert authority and solidify his status as “Sovereign of the Three Realms.” This move demonstrated the Emperor’s skill in balancing power dynamics.

Finally, and most crucially, Sun Wukong himself was a monkey spirit from the mortal realm. It was fitting to counter him using Buddhist forces, which also originated from the mortal realm.
