If you have fear of some pain or suffering, you should examine whether there is anything you can do about it. If you can, there is no need to worry about it; if you cannot do anything, then there is also no need to worry.
Freedom and love go together. Love is not a reaction. If I love you because you love me, that is mere trade, a thing to be bought in the market; it is not love. To love is not to ask anything in return, not even to feel that you are giving something- and it is only such love that can know freedom.
