You don't need to feel it to heal it 

You seem to have the kind of far out, wide-open-minded way of thinking that I find very interesting indeed! I started studying General Relativity, quantum mechanics and quantum field theory to try to discover how to travel faster than light, but these studies led me to spirituality. That's what I made my RU-vid channel to discuss. I'm always happy to find others who think along the same lines!

But happiness and sadness are part of duality ?? I think you should read about non duality philosophy of vedanta
