"No other subject taught in school is as important as Moral Science." Express your views for or against this statement

Image
For the statement "No other subject taught in school is as important as Moral Science." Express your views for or against this statement A school is where the youngsters are taught the fundamentals in every major subject. They are taught Mathematics, Science, English, Computer Science, and regional language - in India Hindi is taught in most schools. Children till primary schools are taught Moral Science, but in higher grades, it needs to be given more or sometimes no attention. The school forgets how this important subject can help the students to become a better person.  Children are enrolled in schools at an early age. They do not know the ethics and behaviours at such an age. Therefore, it is the responsibility of both - schools and the parents - to teach the children these basic yet important lessons. A person without ethics is no better than a non-living rock. Trees also have ethics; every living organism does. Therefore, it becomes crucial to teach the children the eth...

Narrate an experience that shows appearances can be deceiving

Image
A person standing in the railway station dressed in a good looking attire It is a common habit of humans to make judgements at the first look. It does not matter if we are seeing a person or a thing for the first time, our minds do not need to take a second look before coming to a judgement. If we look at a person, we quickly look at his clothes and shoes and come to the assumption that he is poor or rich. The same is the case with things, we decide for ourselves whether a substance is expensive or cheap just by its glittering and glistening. Over time, many learned personalities have taught us to "not judge a book by its cover." Through his various plays and writing, William Shakespeare, the popular eighteenth-century English writer, has sent the message to not fall for outward appearances. I have recently expereinced an incident that explains why is it important to not rely on just outward appearances to make a judgement about a person. I was travelling by train during my s...

Macbeth Personal Notes: Act 1 Scene 2 Setting: The scene is set in a camp near Forres "As seemeth by his plight" An injured sergeant is standing in front of the King Duncan. Duncan asks from his servants who the bleeding man is and concludes from his condition that he is in condition to report the latest developments of the revolt. "Who like a good and hardy soldier fought 'gainst my captivity" Malcolm, the elder son of the king, answers his father and tells him that the bleeding man is a sergeant, who fought to prevent him from being taken as a war prisoner.  "Doubtful it stood" The battlefield stood doubtful. It was difficult to say which side was winning as the soldiers from both sides were tired and as two swimmers who were exhausted holds onto each other so that neither can swim, the soldiers held each other making it impossible for either of them to win. Macdonwald => the name of the rebel. "Worthy to be a rebel" Macdonwald is worthy...

Abhisara - the Tryst Notes

Image
Upagupta, the disciple of Buddha, lay asleep in the dust by thr city wall of Mathura. Lamps were all out, doors were all shut, ans stars were all hidden by the murky sky of August. Whose feet were those tinkling with anklets, touching his breast of a sudden? He woke up startled, and the light from a woman's lamp fell on his forgiving eyes. It was Vasavadatta the dancing girl, starred with jewels, Clouded with a pale blue mantle, drunk with the wine of her youth. She lowered her lamp and saw the young face, austerely beautiful. 'Forgive me, young ascetic,' said the woman, 'Graciously come to my house. The dusty earth is not a fit bed for you.' The young ascetic answered, 'Woman, go on your way; When the time is ripe I will come to you.' Suddenly the black night showed its teeth in a flash of lightning.  The storm growled from the corner of the sky, and the woman trembled in fear. A year had not yet passed. It was eveing of a day in April, in the Spring. The b...
