Rows and beads I carry with ease, ancient tool to calculate with ease.

A part of something you can never quit, It’s all in your head, every part of it. Just thinking of it is the hidden cost So if you’ve solved this riddle, you have lost.

I speak in circles, but never lie, I ask you questions, yet don’t reply. You search for answers, but I’m hard to find, A twist of words that plays with your mind

I rise and fall with hopes and fears, I shift with time, through months and years. I can make you rich or leave you poor, I’m fueled by numbers, but I’m never sure.

Fall too close and you'll not return, Past the line where spacetime churns. At center lies a point, so small, A singularity that swallows all.
