I agree, but then where's the love? Why do we use the word when what it refers to does not exist? Like you said, the world operates fine without it. If we got rid of the word 'love' today the world would be better instantly.
I suppose I agree with you on that, only because its true that people do misinterpret the word "love", and this only because we cant explain love, its way beyond us to simply describe in one word.
The word 'Love' is an attempt to communicate a feeling- a state of being. But you cannot describe it with one word, it is more like a reference point that points you to an individuals perspective on 'love'. You cant capture something as vast, and powerfull as love in a single word. To have or to be? Thats the big one.. If you meditate on one thing, or keep it on your mind, you will aquire the nature of that thing. Example: mediating on God, and repeating "Ram.. Ram... Ram..." In your meditation, or living-meditation, you will begin to aquire the nature of God (whatever your interpretation of God may be). Meditate on Love... Don't seek to Obtain it, seek to BE it. Be love! I recall my Spiritual Teacher giving me a copy of his book, and signing it with the simple words "Love without desire". At first i wasn't sure what to think of it. I learnt it meant to not try to own or obtain love, but recognize it as a state, and to simply BE love... Open your heart, and let the love flow out and in, and ones cup of love with runneth over.
The difference between negativity and optimism is perspective. Love is not an act but a state of being. We are love, that is devotional in nature. We are devoted to our good depending of what that model looks like. All matter has three properties, absorptive, reflective, and polarity. You may choose your own level of composition so to speak. So polarity depends on whether you absorb or reflect. Personal reflection. We cannot escape the effects of our own thinking. Love is without condition. No matter how bad things may seem we rarely lose our devotion to being. This devotion is inherent and therefor beyond what can be taught. However we can remove the blocks we have erected against the perception of it, i.e. our judgments or complaints against the world and our experience. Fear and love do not exist in the same place. Where fear is, love is forgotten. Where love is, there is no fear. All expressions of love are maximal. Depends on what effects you are looking for. If it is some reciprocal response, that is commerce, not love.
