The materialistic mind covering the living entity’s soul carries it to different species of life. This is called continued material existence. Due to the mind, the living entity suffers or enjoys material distress and happiness. Being thus illusioned, the mind further creates pious and impious activities and their karma, and thus the soul becomes conditioned.
