This indeed is a different situation. Major and easily visible evil can be got rid of with no difficulty. As for the minor ones – and those which are not easily visible – are hard to leave; one of the reasons being that one cannot easily discern and locate them. This situation can be compared with the Typhoid which though a serious malady can be treated whereas Tuberculosis which eats up a man from within, is hard to treat. Same is the case with inconspicuous evils which do not let a man perform commendable deeds. These evil deeds are related to the morals and conduct and come to the surface through mutual contacts; with very minor differences love; rancour, jealousy, false show and pride spring up in the heart and one begins to belittle one’s brother. If a man prays merely for a few days and the people praise him for that he begins to make a show of it and the real aim of the prayer – sincerity – vanishes. If God has given him wealth, or knowledge or his family is prestigious, he takes his brother, who does not possess these things as low and wretched. He is very desirous of picking holes in the life of his brother.So far as pride is concerned, it takes different shapes. Somebody displays one type of pride and another person displays another type of pride. The learned people are proud of their knowledge and criticise others in this respect to pull down these brothers. They continue looking for their faults and shortcomings day and night.
