由 (Kanji for freedom / reason)

Onyomi

YUU	YOU want to be free, don't you?

Looks like the God radical, but the vertical line only goes UP. That's because humans always reach UP, searching for freedom.

自由(じゆう) な

freedom ★★★★★
自 (my own) + 由 (freedom / reason) = 自由 (freedom)

理由(りゆう)

reason ★★★★★
理 (reason) + 由 (freedom / reason) = 理由 (reason)

reason (for doing something)

The turtle's head(甲) goes DOWN into its shell.

But you have the freedom to reach UP(由) to the stars.

GOD　(申)is infinite so the line sticks OUT ON BOTH SIDEZZZ.
