Subsequently, the hearts of man can be divided into two kinds, the first of which is the heart of those, who incline to the Beneficent, which is the source of brightness, life, happiness, pleasure, delight and blessings.
The second one is the throne of the devil where narrowness, darkness, death, sorrow, distress and grief are settled therein. This heart is obsessed by sorrow for the past, and grief and distress for the present.
