The meaning of K's quote: "Relationship is the mirror in which we view ourselves"

Had a moment of epiphany today. Jiddu always said "Relationship is the mirror in which we view ourselves". And then proceeded to explain how we have perverted relationships etc. Never made sense. Of course, it could not mean the simplistic 'Gives us a mirror to COMPARE ourselves with others'
because as he already repeats and explains: 'Comparison is the root of all conflict'. So that what does it really mean?

Struck me when I read another quote:

Questioner: Can one love truth without loving man? Can one love man without loving truth? What comes first?

Jiddu Krishnamurti: Love comes first. To love truth, you must know truth. To know truth is to deny truth. What is known is not truth. What is known is already encased in time and ceases to be truth. Truth is an eternal movement, and so cannot be measured in words or in time. It cannot be held in the fist. You cannot love something which you do not know. But truth is not to be found in books, in images, in temples. It is to be found in action, in living. The very search for the unknown is love itself, and you cannot search for the unknowable away from relationship. You cannot search for reality, or for what you will, in isolation. It comes into being only in relationship, only when there is right relationship between man and man. So the love of man is the search for reality.

Love is a process, rather than a stage. If we say we KNOW it, it's already dead, conceptualized, abstracted into a projection of the mind. That is clear. On the other hand, you cannot love something that is unknown. That's illogical.  But he clearly puts it: "The very search for the unknown is love itself". That might be so.
Because it needs sincerity, seriousness, to pay the price, to be ready to lose what you HAVE/KNOW because what you are looking for is much more precious. 'Love' might be a good word for that. But how does this search happen? You cannot say "I am searching for the unknown".

The only way to do this is to start from what you HAVE, from the known. That is your mind. You have to UNDERSTAND the mind, and hence transcend into the unknown. Now the thing is, the mind exists in RELATIONSHIP TO SOMETHING only. It cannot exist by itself. Its content is memories, the responses to them - which is thought, and our subjective extrapolations in between - which can be called our beliefs/opinions. 

So we have to start be examining what we HAVE, our mind. And since mind exists in relationship only - we can understand its working only when it exists. That is, when there is a relationship. Only a relationship gives us the chance to OBSERVE, not compare. To see what happens, how the mind reacts, how thought forms, how fear arises, how we judge. If we don't have a relationship, we are left with nothing but our own concepts(form the past) and we can concoct whatever we want to believe.

Without relationship, we will not get the chance to OBSERVE, because there is nothing LEFT to observe.  There might be a lot to ANALYZE and to conclude from, and add it to the existing accumulated content. But nothing to observe. The process of doing this, of observing, without judgment, without concluding, that is love perhaps.
