It is firmly declared that the steady adherence of transcendentalists to their respective spiritual positions constitutes real piety and that sin occurs when a transcendentalist neglects his prescribed duty. One who adopts this standard of piety and sin, sincerely desiring to give up all past association with sense gratification, is able to subdue materialistic activities, which are by nature impure.
