Wise
If you have an ear for the public's heart, you must be very wise. You can understand everything the people want, and you know how to give it to them because you listen to their hearts so well.
Close your eyes and open your ears. Feel all of the wise things fill you.

All of these wise things are stored in your soul (そう), not your brain. That's where all of these kinds of intuitive feelings live.
Picture your wise soul, living inside your body. Somehow it just seems to know what the public really wants. It's like your soul is connected to their souls, granting you this wisdom.
