Why Ego?

When we pay attention, we find that we keep getting/receiving nourishment, protection or use of all the four orders directly or indirectly every moment, such as:-

We keep breathing throughout the day, keep drinking water from time to time, walk on the earth (means nourishment, protection from the material order)

We eat food two or three times a day, take medicines during illness (means nourishment, protection from the Pranic Order and the Animal Order)

We keep wearing clothes throughout the day like cotton clothes (means nourishment, protection from the Pranic Order), sweaters and shawls (means nourishment, protection from the Animal Order ), raincoats during the rain (means nourishment from the material order)

We live in a house with our family, study in a school, work in an office under one roof (means protection of the material order)

We use mobile phones, laptops for our work and plough, tractor, bulls, ropes etc. for agricultural work (use of the material order, the Pranic Order  and the  Animal Order  and cooperation of humans as a collaborator)

In the family, in the society, we have relations with humans all the time, whether they are of certain expectations or Of contact (cooperation of human order, exchange of values)

We (whole body and I) are always immersed, soaked and surrounded (saturated) in the Space, (means continuous receiving nourishment, protection, energy from the Space/ almighty)

One thing is left out, this body which we have received as a gift is also a gift to us from Material order, Pranic order and animal order. (Human body has originated from the body of some animal's womb)

And I (jeevan) myself? My existence as a result of transition from the material order!!! (development)

Despite all this, instead of gratitude, why do we have arrogance about?
