Knowing is curiosity, love is uniting
Knowing is analysis , love is synthesis
You cannot understand love through your intellect. It is something to be felt.
And anything that needs to be felt ,needs synthesis, not analysis. You have to become one with it to know it

Cannot be expressed, ! That is the nature of love
Tears come , glow comes on your face , the smile comes but words fail to express
Often all these outer expressions give you a glimpse of love and not really the experience of it:)
