Heart - How to purify to make success

Reading of famous book - Sign, Symptom and cures of the spiritual diseases of the heart

Author : Imam Maoulud's Matharat al Qutub

What is heart - before explain the meaning we can check the situation where we commonly use the heart in our common life. Such examples are - Soft heart man, Hard heart man, it touches my heart Or You have taken my heart. What is it and we can say all our emotions and our feeling are kept in some place and that place we can refer as Heart - might be you will get some different definition and definitely I am considering the same . But rather than going to get proper definition it would be a worth to explain the  behavior of heart .

According to modern science - Brain is the central part of our body and its having the responsibility to control all our reasoning skill which should be controlled by Amygdala, Cortex and nonCOrtex, But  as per the Quran - Heart is the central part of human body to control all our emotions and other feelings. Also as per the study from John and Beatrice Lacey in 1970 - Brain sent messages to heart would obey the message.But some time Heart did not automatically obey the message instead it sped up while at other time heart slow down the message. This indicates that heart has its own intelligent to control / address the message.

As you know some people are doing the Crime and they will get the punishment. In fact when someone commits a crime  that time itself he does punish his own heart and that will directly / Indirectly effect whole human being. Quran refers a Kufr and its like covering. And the people who commits the crime apparently cover their heart with  Alcohol , Drugs and sex. But still they are not getting any calm heart and use more drugs, sex to cover their heart. It meant  they are not getting a chance to nourish their mind. Also if we are concentrating in this material world an if you are not accountable of your action and then it treats badly your heart will cause the spiritual death of the heart. Before the death of the heart it shows the symptom of affliction. But if you target the infinite world then your mind should be calm and quite. Quran says - you will get calm heart only with the remembrance of the god.
