On a worldly, material level we may seek – safety, freedom, partnership, children, money, fun, success, your own list.
I think Rumi is talking about the mystery of life – the unseen parts of life. Spirit. God. Goddess. Oneness. Love. Joy. Peace. Compassion. Forgiveness. Isn’t it strange many of the things that matter most to all of us are not material? We can’t see them – we feel them. They are an experience.
An experience Rumi believed is seeking us.
