There is no start and no end to love. You cannot reduce it, you cannot add to it, even if you add your contribution or take away what you want it remains same, its like an ocean it remans same and would always be like this even if you take out gallons of water or add to it, it remains same. Same is love.
What you can do is, see yourself as a part of this vast universe, see your existence in everything, you need to love everything and every part of this universe as your ownself and this will bring you in harmony with this universe. This is teh only way to enjoy life and to live life.
