It is because we are not just the soul but also a body prone to various limitations and evolutionary imprints as well as a mind subject to ignorance and habits, conditioned by the sensory inputs.
Besides it is not enough to know that we have a soul. We need to realise it. It is like a dormant chip that needs to be fully activated for its full potential to manifest.
2) Even if I don’t have access to my psychic consciousness yet, what is the source of my external consciousness? I mean, even when I am not aware of my psychic consciousness, how is it that I feel partially conscious in my external being?
All is the play of One Consciousness-Force that has built creation. The psychic is its purest form. The mind and vital, the external consciousness are its self-limitations. It is like the water drop at Gomukh is purest Ganga. But ultimately it swells up into a river and becomes polluted. So with the psychic being and the external consciousness.
Affectionately,
