In relation to the spiritual openness of the heart...
Those people who possess an expansive (spiritual) chest are able to endure anything that happens to them (things one does not enjoy, difficulties, trials), and he is a person who is not affected by people speaking bad about him and is also one who does not become hopeless quickly.
He is a person who takes in knowledge and information of various types and if a person was to speak or do something bad to such a person, he would keep this in the back of his mind and would not fill his head with the bad things that happen to him. However the person who has a constricted spiritual bosom is the person who, when afflicted with the smallest difficulty becomes upset and does not have the ability to accept and handle trials and tribulations.
The eighth characteristic is that one's soul is humbled. In the language of the 'Arabs, the word [ذلت] means humility and the meaning of the word [ذلول] is that of one that is disciplined. However in Persian, the word [ذلت] carries with it a very negative connotation - thus, it should be said that this characteristic is in the meaning of humility, meaning that a true believer has extreme humility and is humble in the presence of other people.
Whether another person is great or insignificant, he respects everyone and does not wait or expect that others should show respect to him (first). The ninth characteristic of a true believer is that he possesses the trait of not laughing with a loud voice. It has been mentioned in the tradition that the Prophet (S) never laughed with a loud voice - thus, even the laughing of a true believer should be done with dignity and following etiquette.
The tenth characteristic of the true believer is that when he is sitting in a gathering, he strives to learn and gain knowledge in something, and one does not busy himself with backbiting and other things which do not pertain to him or which have absolutely no benefit! [^1]: Bihar al-Anwar, vol.
