Is there any sort of symbolism for Sun Wukong's shootling lazers out of his eyes after bowing to the four cardinal directions? Also is there any other mention of his lazer eyes or is just this one time in the beggining of the novel?
The laser beams only appear in the beginning of the novel.
I've previously suggested in this article that they are one of several events from the historical Buddha's biography that the author-compiler of Journey to the West borrowed in order to make Sun Wukong's early life more familiar. The pertinent section reads:
Upon his birth, the Buddha is said to have āshed in every direction the rays of his gloryā (fig. 3) (Beal, 1883, p. 3). The source continues to describe this light, as well as the Bodhisattvaās first few moments outside the womb:
His body, nevertheless, was effulgent with light, and like the sun which eclipses the shining of the lamp, so the true gold-like beauty of the Bodhisattva shone forth and was diffused everywhere. / Upright and firm and unconfused in mind, he deliberately took seven steps, the soles of his feet resting evenly upon the ground as he went, his footmarks remained bright as seven stars. / Moving like the lion, king of beasts, and looking earnestly towards the four quarters, penetrating to the centre the principles of truth, he spake thusā¦ā (Beal, 1883, pp. 4-5).
The historicalĀ XuanzangĀ (on whomĀ TripitakaĀ is based) notes inĀ his travelogueĀ that the Buddha even walks towards the cardinal directions: āAfter he had been born the Bodhisattva walked seven steps unaided to each of the four quarters ⦠[u]nder each step a large lotus flower sprang up from the earthā (Xuanzang, 1996/2016, p. 158).
Wukong too produces a great light in every direction: āHaving learned at once to climb and run, this monkey also bowed to the four quarters, while two beams of golden light flashed from his eyes to reach even the Palace of the Polestarā (fig. 4) (Wu & Yu, 2012, p. 101).
Therefore, both shine their lights in the four cardinal directions.
