The study of love is an emerging field. Perhaps the leaders in the field are a group called The Institute of HeartMath who have found that we have many physiological, psychological, and social benefits when we're living with greater love, care, and compassion.

The fifth doorway to experiencing Love for No Reason is the Doorway of Communication, which corresponds to the energy center located in the throat area. This doorway relates to speaking and listening with compassion, rather than judgment. There are some wonderful tools and techniques available to help us speak and listen with compassion that I've included in this chapter.

The fourth doorway is the Doorway of Openness located in our heart center. It has to do with being open to both giving and receiving love. It's not just about being able to give, but it's also about the ability to be open to receive. There's a certain vulnerability in receiving. When we truly take in and appreciate all of the gifts of life, then our hearts are truly open in love.

The concept (of happiness) is universal. In Buddhism, it is called causeless joy, in Christianity, the kingdom of heaven within, and in Judaism it is called ashrei, an inner sense of holiness and health. Is Islam it is called falah, happiness and well-being, and in Hinduism it is called ananda, or pure bliss.

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.

It is support that sustains us on the journey we've started.
