"3. These are the hindrances: the darkness of unwisdom, self-assertion, lust, hate, attachment. Let us try to translate this into terms of the psychical and spiritual man. The darkness of unwisdom is, primarily, the self-absorption of the psychical man, his complete preoccupation with his own hopes and fears, plans and purposes, sensations and desires; so that he fails to see, or refuses to see, that there is a spiritual man; and so doggedly resists all efforts of the spiritual man to cast off his psychic tyrant and set himself free."
