How do you demonstrate your unity as a couple? By getting married? That’s not enough.
During your actual wedding ceremony, in addition to your vows, the kiss, the rings, and the license, you should throw in another symbol. You need to make sure everyone gets that YOU’RE TOGETHER, and marriage isn’t 1 + 1 = 2, but 1 + 1 = 1. Sharing a glass of honey water, lighting a unity candle, and making a vase of unity sand all serve this purpose.
Or, you could create a painting.
