So the difference between most books about love and Love For No Reason is that traditional love books focus on love as a stream of energy between two people, whereas this book focuses on love as a deep state of being that you can live in no matter what's going on in your life.

To make the quickest progress, you don't have to take huge leaps. You just have to take baby steps-and keep on taking them. In Japan, they call this approach kaizen, which literally translates as 'continual improvement.' Using kaizen, great and lasting success is achieved through small, consistent steps. It turns out that slow and steady is the best way to overcome your resistance to change.

What would our lives be like if we could all be happy no matter what?

When we're feeling fully alive, we're able to fully feel love. This doorway also relates to feeling our feelings fully. Not suppressing our feelings of anger, sadness or grief but allowing them to be felt. What's amazing is that when those feelings are felt, they actually dissolve into love.

Like your weight set-point, which keeps the scale hovering around the same number, your happiness set-point will remain the same unless you make a concerted effort to change it.

I did some more soul searching. I asked myself, "What do I want more than happiness?" and there was only one answer - the only thing that trumps happiness is love. Not the kind of love we are normally taught about, but the kind of unconditional love that is a deep inner state which doesn't depend on any person, situation or a romantic partner. That's how I define Love for No Reason: it's an inner state of love.

The first doorway (or chakra) is what I call in the book, the Doorway of Safety. This doorway relates to feeling safe in life and being present in the here and now. It's only when we are really grounded and safe that we're able to relax and open up our hearts.
