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 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 found the best thing to do is to really be loving, kind, forgiving and compassionate with yourself. There are some wonderful practices for that which I talk about in Love For No Reason.

The second doorway has to do with vitality. It's about feeling alive, vital, and feeling the life-force flow through us. This doorway is also known as the creativity center and it houses a great sense of aliveness in it.

I believe love is why we're here on the planet and that ultimately it's our purpose for life. They say people who've had near-death experiences often report back that at the end of our lives we have a life review and we're asked one question, and that question is, how much did you love?

The sixth doorway is the Doorway of Vision. This relates to seeing with the eyes of love and corresponds to the energy center located in the third eye area of our forehead. When this doorway is open, we're more able to see life through love instead of differences.
