Do souls exist? Like everything we think and feel comes from our mind, doesn't it? [I Am Still Searching For My Soulmate]

Buddha says there's no such thing as a soul. We are a pinch of energy in the field of buddhanature smothered in karma. I would call that a soul. What we think and feel is a product of our brain and that ends when we die. And our brains are notorious liars.

No on the second question. Apparently the heart has it’s own kind of system that’s like a brain. 🧐 Guess that’s why the heart and actual brain conflict.

This is a tough one. I'd really like to think we have a soul. Simply because then we go to heaven and live on. But if the soul is the only way of understanding the conscience then I guess its sad to think when the brain dies that's it.
But like I mentioned to someone here, there have been stories from organ recipients that claim they have a connection to the previous person, manifesting in sayings or new preferences for food, or just a overwhelming feeling of what the person was like.

The body is a complex thing and I think we are only 10% if not less into really understanding what exactly is going on.
I personally cant give a clear answer on this subject matter.

I like to believe mine does. To each their own though

If it’s not science, it’s superstition.

After we’re conceived, it’s all chemical reactions. Especially hormones.

Dunno. I cant prove if they do or not. It's nice to think I have a soul, tho
