The love for her dog was evident in her posts bless her, her dogs safety and future would have been a priority I have no doubt about that.
I think she took her dog with her. If you read her posts about her dog, the evidence for this is strong.
SA is not a good death at all. PN agreed with a press statement put out by a medically qualified person in The Netherlands that it was "a horrible death". Later, PN suggested that it was quick, but with no evidence for that. I suggest the evidence at her house suggests it wasn't quick at all.
That circular thing in the yard that was burned. It was the chair she used. See the last pic she posted. Nothing outside was burned, except the chair and its base.
Nothing about this incredibly sad event was good or peaceful, looking at the evidence. Peacefulness was the highest priority for SiArc, and she went to great effort to create the gentle, beautiful meditative space where she would have a smooth passage to the "next realm", as she believed. She timed it with the eclipse.
There was
nothing ok about all this. It was
not what she wanted. Personally, I find it distressing. Yes, she's gone now, and she wanted that, but she wanted it to be the opposite of what seems obvious ended up happening. You get one death only. SiArc's death was not the gentle transition that was so very important to her. It looks like it was the death of her worst nightmare.
