Love is a level of maturity between people with things that are calibrated to the depths of awareness and understanding. The closer you find someone to your conscious reality the more of your reflection you will see because you want to embrace yourself.
Sometimes that is done through people and animals. Much of love is a conceptual reality and many people have a limited conceptual reality and cannot think outside their box until they return to it in their grave.
Sometimes in life, it is difficult to be hue, the light that you are. You have to go through a prism and separate the light into fragments of colour that only other people see, and you lose the wholeness of yourself so you are reflecting only how people see you.
The more you get integrated into who you are the clearer you become clear light. The more fragmented you are the more you have to compare the colours and the wavelengths and this is the process of living life on this planet.
When you become clear with love you combine the colours that you are, not as a rainbow but of pure light and a rainbow of fragmentation of all wavelengths into you being better integrated.
