Answer: The unity depends only on the annulment of the egoistic personality, not on the total annulment of our individual personality. If I see that the ego only harms me, I want to become a totally different personality.
The personality remains and becomes free. Today I am under the domination of the ego and am drawn to pleasures such as food, sex, family, money, respect, knowledge, and control and I twist and turn in these desires, constantly yearning to fill them as much as possible. Thus I only steal from myself and there is nothing left of me.
