KanjiJLPT N3
Equal

etc., and so forth, class (first), quality, equal, similar

Mnemonic

The bamboo stalks growing around the temple are all equal in height. The monks trim them daily, believing no bamboo should rise above another—just as no monk in the temple should consider himself above his brothers.
Additional thoughts
Picture a Zen garden with perfectly uniform bamboo rows. The temple's philosophy of equality extends from nature to the monks themselves—everything is kept level, nothing stands out.
Quick recall
Bamboo at the temple is trimmed so every stalk stands equal.
