The best way to keep relationships happy, healthy, and supportive can be summed up in one word: appreciation. What you appreciate, appreciates. When we demonstrate our appreciation for the support we receive from others, it reinforces that behavior and deepens our connection to them.

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.

I've come to see that I have two choices in how I approach change: I can either resist change or be open to what's ahead and feel the peace that "all is well in the universe." When I lean into the latter, I feel excited about the future.

HeartMath found that five minutes of feeling love and care can strengthen your immune system for up to six hours, whereas five minutes of feeling angry can weaken and suppress the immune system for six hours. Love releases very powerful, beneficial chemicals into the body.

One of the things that happens when we're feeling more love and care is that we go into what's called "heart rhythm coherence," which you can actually measure and monitor on a computer screen. It's also possible to train yourself to go into heart rhythm coherence at will.

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.

Taking ownership of your happiness has two aspects: Accepting that being happy is up to you and that you have the ability and power to be happier by changing your habits. Taking "response-ability": responding to all the events in your life in a way that supports your happiness.
