HARMONY

An enjoyable aspect of any relationship is a deep and abiding sense of harmony.
Harmony doesn’t mean that the two or more elements in the phenomena are the same. It means that even though the two elements are different, they are not discordant, or in contradiction or conflict with each other. On the contrary, they complement and enhance each other. One makes the other better.

So, it is not that two people in a harmonious relationship are the same, or talking about/ doing the same thing, or always in agreement, or in the same physical or mental state. Harmony means that the difference does not cause discord or hostility. It leads to learning and growth and provides succor and relief.

Harmony implies that there is acceptance and appreciation of the difference. There is no attempt to pull the other to one's point of view, activity or state of being. There is trust and receptivity that allows one to embrace and be infused by the state of the other.
It is not really the content of what is said or done in a harmonious relationship, which is always remarkable or special. It is the trust, acceptance and understanding that accounts for the soothing and uplifting nature of the experience.
