I came across this particular question which put me in deep thinking.
A devotee of Adhiparasakthi, Melmaruvathur, ADVAITH, had asked this question in their forum.
He asked if anyone else noticed the resemblance between the Tamil Om Symbol and the image of brain.
I see a lot of resemblance.
I wonder if there is any connection.
Skeptics may argue that the picture of brain we see is sideways and not front. But hey, why do we always see it in sideways, and not front. Because I guess it represents all the important parts of the brain. When you google for brain, and go to images, this is what you see.
