There are countless ways to express love. It could be in the simple act of giving something, such as a flower, a book, or a diamond ring. Perhaps the giver has created something of him or herself, such as a painting or a sculpture.
Love is also expressed without objects. Maybe it is shown in a simple hug, or a passionate kiss, or in the act of putting toothpaste on your love's toothbrush. It could be a kiss "hello", or a kiss "goodbye".
There is also sustenance. I believe cooking a meal for someone, or maybe even just bringing them a cup of tea when they need it, is a great way to express love. Food is essential to everyone, just as love is.
Love is expressed and received differently by everyone. By being open and compassionate, I think we can all be more ready to both express and receive love. It is the foundation of humankind!
