You say it hurts to love. Because you love and then get scared. Fear cuts off your knowing of love.
So it hurts, to connect and then disconnect yourself. You think that loving is what is causing the pain. But it's the blocking of love that hurts to much. When you get scared and flee. WHen you get scared of all the things that could go wrong.
But if you are loving, you're not thinking of all the things that could go wrong. There are only things going right.
Start saying "I love you" to your reality. Make it your chant, your background music, your mantra, your point of center.
When you love your reality it will love you back and nothing could possibly "go wrong".
You'll just see the unfolding of life as love. And it feels so good. Like playing with magick on rainbows with everyone you love. And flying and lights and details and fractals and kaleidoscopes. And kitties and seedy underbellies and whatever crazy dream you might have.
