Now join your hands, and with your hands your hearts.

The line urges a union that is simultaneously physical and emotional: clasping hands should be matched by a sincere joining of hearts. In Shakespearean terms, it suggests that outward gestures—handshakes, vows, public reconciliations—are incomplete unless they reflect inward concord. The phrasing also plays on the symbolic role of the hand as a token of pledge or contract; to “join hands” can mark agreement, marriage, or peace-making, but the speaker insists that true harmony requires affection and goodwill as well. The couplet-like balance (“hands…hearts”) gives the sentiment a ceremonial, communal feel, as if spoken to seal a collective act of unity.
