i read this article this morning and thought i should probably share here, read until finish :)

Love everyone and everything, without attaching strings and without judging them.

Have personal regard and respect for the people you meet. Treat them as equals and not inferior or superior in any way.

Work on the principle that everyone is, at heart, good. Assume that although they may do questionable things, the person underneath is fundamentally pure.

If you love someone unconditionally, then you cannot judge or blame them or find them bad.

Unconditional love works well in relationships too. If you do not put conditions on your partner, then you open the doors for a much more fulfilling and trusting relationship.

If universal unconditional love is difficult for you, start with your family and people you know. Or just try it in a single conversation.

Unconditional love means love without condition. It means giving love without expecting anything in return, including any reciprocal love.

This can be a difficult route to happiness, yet it is one where a great deal of happiness can be found. The more you can stretch your love, the happier you can be.

Unconditional love is nothing to do with romance. It does not want anything from the other person, though it may want everything for them. It is not about desire and possession; it is about appreciation and concern.

Unconditional love is something to do with parenting, yet parents want so much for and from their children that much of their relationship is far from conditional.

One principle, from the field of psychoanalysis is that we have an inner true self that is too vulnerable to expose, so we cover it up with the mask of a false self. Unconditional love is of the true self. Perhaps also it comes from the true self. In this way, it may be considered as the most real and truthful form of affection.

By showing you care about that inner core, you can get much closer to the person and connect with them in a more truthful and rewarding way.

get this article from : The neural basis of unconditional love. Psychiatry Research,172(2):93-8

here is my opinion : a good friend of mine told me that 'love may fade away, but the commitment stays.' but I disagree with this statement. at this point you might think it's right. but I think, the situation is people may get bored with 'the relationship' but not with the person. because I had figure it out, thing which make the commitment stays is an unconditional love. without unconditional love, you may not be able to stand thousand days with the same person, commitment has nothing to do with it. without that, people won't be 'really' with someone through the bad, they just want the good. trust me, all the successful marriages need an unconditional love to survive.

so, after you meet someone who you think a worth-loving one, why cant you give him/her an unconditional love for free?

Love is always patient and kind; it is never jealous, love is never boastful or conceited; it is never rude or selfish; it does not take offense, and is not resentful. Love takes no pleasure in other people’s sins but delights in the truth; it is always ready to excuse, to trust, to hope, and to endure whatever comes. Love does not come to an end -1 Corinthians 13:4
