Love is such an uncertain concept. It is feeling. It is like a flame. The passionate feelings or chemical reactions between human souls are not tangible thing. It comes, and it might stay, or go. It might be there forever, or just a second. We can not control those. It is scary. At least I feel scary. Yet, we look for love.
What if we accept "Yuragi" in our lives? What if we allow ourselves to "Yuragu"? And stop fixing stuff? Unknown means possibilities. Once the door is open, we might feel we are a part of mother nature - the oneness with the world.
