The kingdom is this world. Malkhut has "nothing of her own" — every light she holds is received — and yet she is the purpose of the whole emanation: a dwelling below. She is the Shekhinah, the divine presence in exile, the Sabbath bride, the community of Israel, the earth, the spoken word (for she is also called Mouth). All the drama of the Zohar — exile, longing, union — is her story. The end of the action is the first thought.
"She is the gate through which all enter" — the Zohar makes Malkhut both the last sephirah and the door to all of them: you cannot reach the Tree except through her.
