Dear, dear GS...
I'm not a very religious person - that said, I've had what can only be described as intensely spiritual experiences.
I'm SOOO glad you've found the wavelength of comfort and peace that always co-exists with the pain, grief, loss and yuck of this life. It's far greater than any of the "bad" you've experienced via your parents & FOO experiences, or so it seemed to me when I had those moments. What's still a mystery to me - and that's just fine, I don't need it explained - is why and how those validating and confirming experiences remain available in their full-strength version to me... all these years later. Unlike garden-variety, everyday "happiness" that can be wrecked by the next uncomfortable or irritating situation - this kind of comfort sticks around and has some mysterious auto-start mechanism for me. It kicked in the night we drove home in the wee hours of the morning, knowing MIL was making her final earthly jouney.
From those kinds of experience - a sort of "mother mary comfort me" moment - I've learned that love is the most powerful emotion in the universe and that it makes possible the ability to grieve and mourn in a healthy way... a letting go with love. And it exists beyond any one person's ability to control it, give it or receive it. It belongs to God or the Universe... not to people - yet it's always there, ready to be tapped - or auto-starting by itself - when we need it most.
