Dear Vaagmi ji,
So what do we infer from this?
Its shows that the innate nature of humans is to be a one point focus and be totally oblivious of the surrounding.
Externality ceases to exists when we are focus on a single activity. Its almost in a semi meditative state.
I am using the terminology semi meditative becos when using a smartphone..even though we are focuses on using it but the mind is continuously stimulated by inputs..so its not anywhere totally close to meditation but only 50% there..that is the ability to detach ourselves from the surrounding to indulge to be on a smart phone.
That is why people even die getting hit by a car or train becos they were totally unaware of the surroundings.
Going by this some Indian Guru jis should come up with effective Meditation Apps to make the mind of users focus into a 100% meditative state.(there are some Meditation Apps anyway..but God knows how effective they are)
