There is the Self that ordinarily identifies itself as 'stephenw' and/or 'satish.'
That is the normal, everyday 'consciousness' and 'identification' - which makes the world go round..and round!
To find out intellectually what 'that self' is, you can undertake a thought experiment.
Close your eyes. Think deeply.
Imagine you have lost your left leg in a car accident.
Is the self still there? Yes. Therefore, 'self' does not necessarily require the 'left leg' for its existence.
Imagine you have lost both of your eyes in a car accident.
Is the self still there? Yes. Therefore, 'self' does not necessarily require "eyes" for its existence.
The self remains even if non-critical areas of the brain are removed!

Does the self remain if one is deprived of all the 5 senses?
Sensory deprivation - Wikipedia, the free encyclopedia
This self exists because it 'PUTS ITSELF TOGETHER'
&
it does NOT exist because it 'PUTS ITSELF TOGETHER!'
It is possible to experience 'another' consciousness in which the 'Self' or 'Me' ..Fills the Void Completely....! Now, this Self comes to understand that WHAT lies beneath the self's of 'stephenw' and/or 'satish' is this same Self. That the self's of 'stephenw' and/or 'satish and a billion other names..will come into existence and disappear...like the Waves of an Ocean... but the Deeper Self..is there..always...like the Ocean.
Once this is understood, the Reality of Waves disappears...though you will still be seeing waves when you walk along the Beach of Infinity!
