When you take the time to think this through, such a position becomes ridiculous. Individuality, personality, personal consciousness, and 'understanding' are all interdependent upon and interactive with the social and physical environment in which you live. These attributes, or 'accretions', as I call them, have no place in what you are calling 'the spiritual world'; they are part and parcel of THIS world. You will stick out like a sore thumb when you bring all of that excess baggage with you into 'the spiritual world'. Having said that, it is clear that you are still living in the world of duality, in the subject/object split that exists only in your mind. There is no such thing as 'the spiritual world' vs. 'the physical world'. There is only one world, and this is it. 'Spiritual' and 'physical' are just notions/distinctions you maintain in your mind as the result of your social indoctrination and learning. Once you understand this, the world will come alive for you, instead of it being an object of the intellect.
Your attributes are temporal. They are not who you really are. They are temporal manifestations of the source. Who you really are is the source itself, pretending not to be the source. Why is another question. It's like the actor and the character he portrays. When the drama is over, the mask is put aside and the real person comes into play once more. The personality of the character is no more. However, were the actor to become so involved with the character that he actually believed himself to be that character, and to completely forget who he really is as the actor, then we might end up with a case like yours, in which the there is a permanent 'soul' with permanent attributes. It would be a case of the snowflake thinking it is the point, forgetting its true nature is attributeless, formless water, and that it goes on forever as a snowflake.
