„Differences and similaries
How much is important to have differences and similaries between two people in a relationship or other? And how can combine between them? For tastes, preferences, experience, etc?
It is like Unity in diversity. Partners are always diverse but there is always a thread which ties them together. Rule of polarity is also to attract opposites. It could be gender, likes, emotions, intelligence and so on. What is most important is similarities in thoughts to accept each other as they are over differences they carry. Giving and receiving can combine them well.
