Prabhupada nicely explains the “mind”
December 29, 2014 in Damaghosa Dasa by Yasoda nandana dasa
The material mind is like a sheet of impenetrable darkness that completely shuts out the light of the soul. The soul is by his nature self-effulgent and has nothing to do with the material mind which acts as a screen to cut off the light of the soul from the view of the observer who uses the mind for such a purpose.
