I do not want to talk about theory or philosophy here; I really want to talk from my personal experience of Unconditional Love.
It took me a lot of work, time just asking myself what I wanted, listening to that inner voice or guidance, before I realized I prefer the experience of loving what life is offering to not loving what life is offering. AND, it took a lot of work to cut through all the beliefs I had that restricted or limited my opportunity to love. I had so many beliefs that told me I cannot love this or I cannot love that. With time and a willingness to look at these beliefs, I eventually saw through ALL of those beliefs that limit my love.
I LOVE to love. Love is the richest experience I have ever found, or at least love is the word I use to describe the richest experience I have ever had. Therefore, I had to ask myself, why would I create or allow any conditions to exist that would limit my experience of love?
With a willingness to examine my beliefs and doing so, I realized that there are no good reasons to limit my love.
So now, I can and often do Unconditionally Love ALL that life has to offer.
When I love unconditionally all that life has to offer then I am experiencing Unconditional Love.
It does not matter if another or even the whole world can love me unconditionally, if I do no love then I will not know love. As someone else once said, the measure you give is the measure you shall receive.
Does this mean that I will always CHOOSE to love what life is offering? No! Part of life is the experience of fear, hate or whatever emotion life is offering, and I want to have these experiences too. With consciousness or awareness that I have a choice on what type of emotion I experience, I have the freedom to choose the experience of love or not, it is not conditional upon external situations.
I do not need a complicated philosophy or theology to allow me to love unconditionally. I do not need any person or object to practice the art of love. I choose to love unconditionally when love is the experience I want to have.
I also find that with this unconditional love in my heart I have less or no need to see others change, yet I am available to demonstrate that change is an option if you should want it. Loving what life is offering makes me a softer, kinder person.
