This is something to do with the Virtual existence that modern machines are now able to map and relate.
For every human being there is a virtual existence that is interwoven and entangled with the body.Once that is disconnected then we have just the body and the person is no more.
This has been systematically and logically explained in Patanjali yoga sutras, vedas, upanishads and the Gita which ancient texts I have been reading for over 30 years now.
The Brain as you know is the hardware and the O/S is your belief system built during your existence as a virtual being which may or may not span more than one bodily journey. Dont get confused over it and this can be easily understood logically and with proof.
Now coming to this virtual person he has vairtual parts like Mann,vritti,chitt, Buddhi Aatman etc which have clearly defined roles that they perform.
These are the places were the feelings are experienced and recorded via the body brain and the neurons. To Simplify understand them as some organs doing certain functions just like we see with the eyes but not in the eyes.The eye is just a signal reciever and transmits images to the brain.The image processing is done in the brain and the associated feelings are experienced in the virtual organs. We feel delighted in seeing an old friend and are afraid when seeing a snake.
Once you understand this and know that you can never never fool the virtual self which is always just and gets hurt when you hurt anyone you accomplish eternal bliss.
I am practicing it with ease in my daily life and longing to make this world full of humans who do not want to hurt simply by being selfish and not wanting to hurt themselves.
Looking forward to learning more and sharing what I have learnt I remain humbly grateful and eager to see more such posts.
