The concept of individuality that we now know is fake. It is not real. Hinduism tries to find what is real individuality.
Individuality consists in the recognition of something as ‘myself ’. I cannot point out to my body as myself for it is constantly in flux, every moment it is changing. I cannot even point out to mind and senses, for they too are incessantly changing. And the ego is so eluding, I cannot find out what it is and where it is. If this is the situation, what constitutes my real individuality? If I can assert that I am the spirit, there lies my real individuality, for the spirit is the one unchanging element in my personality.
To realise my spiritual nature, I have to separate myself from the products of Prakriti such as intellect, mind, senses, and the body, which are the different segments of my individual personality. All the sufferings that is unavoidable in this embodied state are due to my identification with these products of Prakriti.
Swami Vivekananda writes on the topic:
As Swami Vivekananda points out, we are not yet individuals, because of our identification with body, mind, and senses, and so on, which are constantly changing.
He says:
Individuality means what cannot be divided. How can you call this individuality? One hour you are thinking one way, and the next hour another way, and two hours after, another way. Individuality is that which changes not — is beyond all things, changeless.
