21. Amīr al-mu’minīn, peace be upon him, said: The consequence of fear is disappointment and of bashfulness is frustration. Opportunity passes away like the cloud. Therefore, make use of good opportunities. 
 However had a thing may be regarded among the people and however it may be looked down upon, if it is not really bad then to feel bashful about it is quite foolish, because it will often cause deprival from things which are the source of successes and achievements in this as well as the next world. For example, if a man fears lest people may regard him to be ignorant and therefore feels bashful in asking an important and necessary issue then this misplaced bashfulness would result in his being deprived of knowledge. Therefore, no sane person should feel bashful about making enquiries. Thus, an old man who was learning despite old age was asked whether he did not feel ashamed of learning in old age and he replied: “I do not feel shame for ignorance during old age, then how can I feel shame for learning in old age.” Of course, to feel shame in doing things which are really bad and mischievous is the essence of humanity and nobility; for instance, those immoral acts which are bad according to religion, intelligence and ethics. In any case, the first kind of bashfulness is bad and the second one is good. In this connection, the Holy Prophet’s saying is that: Bashfulness is of two kinds, bashfulness of intelligence and bashfulness of foolishness. The bashfulness of intelligence is knowledge whereas the bashfulness of foolishness is ignorance.
