crude, simple, plain, docile
朴 centers on natural, unadorned simplicity: something crude or plain in its raw state, and by extension a docile, unpretentious nature.
朴 combines 木 (tree) with 卜, which likely contributes the sound. The idea of unworked wood extends to simplicity and plainness.
A tree 木 beside a simple divination stick 卜 suggests raw, unshaped wood. Think of a plain, crude piece of timber—simple and docile.
For ボク, imagine a simple wooden box: box -> ボク, and the plain box reflects the kanji's crude, unadorned nature.
