I like the Islamic prayer you quoted. I believe in it truly. It is God who has been sustaining me with me doing nothing and no power of my own.Sravna..to some extent I dont think anyone of us need to " place ourselves in a box" based on abilities be it intelligence or brute strength.
Dont you think that is just way too much bodily identification as " I am ONLY the physical body"
There is something called the Subtle body which has imprints of all lives we had taken be it animal or human of any race or varna or even insects or plants..all those imprints are also there.
As you must be knowing nothing is ever destroyed..so we are still very much what we were from first day of manifestation when the world started hence you would see even some Brahmins who were born in veg families adopt eating meat as adults because some previous birth imprints could be acting up.
So why give ourselves too much bodily identification.
If one is able to move beyond all these gunas, the imprints would be rendered inactive and one functions in the Atmic level.
Honestly Sravna, this is what Nahi Nahi Rakshatin Dukren Karane is about.
Just surrender to God and move beyond your intellect and function at an Atmic level where all free will is lost and only the Divine will works through us and we are merely an instrument and nothing more.
There is an Islamic prayer to recite before eating food which translates as
" All praises be to God who sustained me with this and granted me this food to me without any doing of my own or without any power of my own"
Ok, one would have worked, earned money, bought the grains/ vegetables and cooked it yet one is not attributing anything to self effort and thanking God that He made everything possible.
Its a good prayer, it removes our ego of being the doer.
