sphere, ball
璧 centers on a precious round object: a jade sphere or ceremonial ball. The meanings 'sphere' and 'ball' both point to a valuable, perfectly shaped orb.
璧 combines 辟 (which likely contributes the sound) with 玉 (jade), indicating a jade disc or sphere. The exact historical development of 辟 within this character is uncertain.
The bottom part 玉 is jade, and the top 辟 looks like a ruler or authority figure. Imagine a king holding a perfect jade ball as a symbol of power: 璧 is that precious sphere.
For ヘキ, picture a heckler throwing a jade ball at a performer: heckle -> ヘキ, and the ball is a valuable sphere.
