LOVE Vs UNDERSTANDING

Hi Again....
This time the topic is which i had seen believing in since the last few years. Can something called LOVE exists or is it pure UNDERSTANDING which takes two different people to all the happiness life it has, for one another or is it how well we understand each others need and give each other company when they require the most. The answer is rather not easy.
Now I define LOVE in my own words, its the feeling which we develop for one another just by seeing a few actions which seem to impress us and we feel good about it, pure actions and their inferences in our own way or rather what we see we believe. The company of one another becomes so insepeperable that we just keep thinking about the other person and what they did and how did it impressed us. The actions done could have been deliberate or instinctive, that is just not what comes in our mind and we blindly believe what we see and the goodness attached to it. Well its an amazing feeling which if had not existed the world would not have been so wonderful for young hearts.
Now the next is i.e UNDERSTANDING its also inseperable part of LOVE, till the time we do not love someone we shall never care for that person. But that is not what UNDERSTANDING is all about its a step further into the realities of life, when you know the other person needs to leave its LOVE that makes you cry but its UNDERSTANDING which says GO and BE HAPPY wherever you are, its love which makes us remember Birthdays but its UNDERSTANDING which makes the other person know that somewhere that we still care and remember the ocassion even though we could not say it in so many words.
Its LOVE which makes us laugh at the silly jokes cracked by the other person but its UNDERSTANDING which makes us scold/give VISHESH TIPPANIS on any subject to the other person when we feel that might help the other person. Its LOVE that makes us hold the other person from saying goodbye but its UNDERSTANDING that makes us realise and accept that for the other person's betterment we need to let them GO, but its pure un understanding when the other person keeps saying 'I LOVE YOU' and we never understand the depth of it and realise it jsut when its time to part and we desperately want them to stay but its now gone for ever, then we think either come on she could have waited some more time or i was a DUD not to understand that(choose whatever fits or maybe both). Its LOVE when we forget about our parents, who have raised us with all the pains anyone could ever take, and go ahead with our decision to go and get married to a person of our choice inspite of them not being willing for it. But its only understanding when either we decide to convince our parents on the subject and ensure they do not get hurt by our decision and take care that in future they never repent allowing us to get married in an environment where they could not get ever get comfortable into, after spending their entire life in another set of condition, in such case the level of UNDERSTANDING with our parents is far beyond what we can expect ,or the other one being letting the person whom we love so dearly go with a person who belongs to the same kind of family as she is where there would be lesser number of problems to face, the major one being exchange of thoughts between everyone would be more simpler. And mind you in the latter case the most difficult task is to inspire the person we love dearly to go in for the other person.......... depth of this is far beyond words.
Few people get love before understanding(love marriages), some get understanding before love(arranged marriages), some get only love(broken love marriages/mutual parting of ways), some don't get any(estranged relationships) but none get understanding alone as Love has to be there to develop understanding, so all of us who feel there is no love but only understanding need to rethink on this aspect.
Now all this is just a thought one can think upon while writing. Hope this gets me BOOKERS' at least...
Looking forward to get a combination of both LOVE and UNDERSTANDING where i can say my thought on this particular topic has borne some fruits for my own self...
