I believe I have wonderful news for those who, when confronted with unconditional love, begin to be grateful for it but then are conflicted if their gratitude is real, or is it manipulative. For example, if I feel that you love me unconditionally, I may thank you profusely, but since someone has told me that gratitude for things multiplies them, I often wonder if my gratitude for you is real. Or am I being grateful so I can have more of you, so that you never leave me. It also makes me competitive, how can I pay back?

The good news is that, once it is fully accepted that you love me unconditionally, it means that I have no fear you will leave. When I have no fear that you will leave, my gratitude no longer has any purpose. In a sense, when I believe you will give me everything, regardless of what I do or who I am, I will not be able to manipulate you anymore. How can I?
So, accept the moments of unconditional love. Go fully in them, and you will see that just as someone can unconditionally give, one can unconditionally receive.

When we accept unconditional love fully, we can only be grateful.
