think, be methodical
侖 centers on orderly thought: thinking in a structured, methodical way. The given meanings 'think' and 'be methodical' are two sides of the same idea of systematic reasoning.
侖 is thought to combine 亼 (a cover or gathering) with 冊 (a bundle of bamboo slips used for writing), suggesting organized records or orderly arrangement, which extended to methodical thinking.
The top 亼 looks like a lid or a gathering cover, and the lower part resembles a neat stack of bamboo slips 冊. Picture a person organizing thoughts like arranging bamboo slips under a cover: methodical thinking.
For リン, imagine a methodical thinker named Lynn who always arranges her notes in perfect order: Lynn -> リン, and her organized thinking matches the kanji's meaning.
