Is Ahankara simply a representation of the proportion of each of the unas in a person?
Ahankara is the sense of individuality. The notion of 'I am the doer'.
Technically speaking, it is derived from total sattva taken from all the five elements.
It is necessary for us to exist as sarira in one piece.
We can imagine ahankara to be like a magnetic field around a magnet. The subtle and gross elements align themselves in its field to create a sarira. They fall apart when ahankara is removed.
Colloquially, ahankara is spoken of as an egoistic word to be shunned. However, in vedanta, it is characterless like a plain television screen. It displays the knowledge/ action/ intellect of the person which can be predominantly satvic, rajasic or tamasic.
Thank you Sir. Does this mean even a Gyani or Jeevan Muktha has Ahankara? If Ahankara is simply displaying the knowledge of a person, does it mean it is same in all?
Yes. By definition, Jeevan Mukta will need ahankara, for us to see him as one individual. But, for him, he would have renounced ahankara and would have attained Jeevan Mukti.
So, Swami Anubhavanandaji says in one of his talks on Panchadasi, one can attain jeevan mukti, but one cannot become a 'jeevan mukta'.
Instrument of 'Vision' is same for all- what we can see would be many objects
Instrument of 'Touch' is same for all- what we can feel would be many different things
Instrument of 'Manas' is same for all- what we can think differs from person to person
Similarly, instrument of 'Ahankara' is same for all- what proportion of gunas we can have in it differs from person to person.
Thank you sir
