The mind is a dual affair objective and subjective. The objective mind sees all， hears all， reasons things out. The subjective mind stores up and only gives out when the objective mind sleeps.
And as few men ever cultivate the absorbed， reflective or semi trance state， where the objective mind rests， they never really call on their subconscious treasury for its stores.
A mall in commerce， where men prey on their kind， must be alive and alert to what is going on， or while he dreams， his competitor will seize upon his birthright.
