At the age of six, Naren was sent to primary school. When seven years old, Naren joined the metropolitan Institution founded by Pundit Ishwar Chandra Vidyasagor.

The life and messages of Swamiji are a source of great inspiration to many in their individual as well as collective life. His words give courage to a dropping soul, his message brings new hope for a sinking nation. Swamiji was the embodiment of strength and if all his teachings were to be summed up in one word, that word would be ‘’STRENGTH”-a dynamic strength. It is for the want of strength that individuals fail in life, nations suffer and the world is in torment.


Some messages of swami Vivekananda :


# ‘’ who loves all being, without distinction, he indeed is worshipping best his god.’’
#  Religion is one, but its applications must be various.
# Unselfishness is God
# No work is secular. All work is adoration and worship.
# Arise, awake and stop not till the goal is reached.
# All power is within you, you can do anything and everything. Believe in that; do not believe that you are weak. Stand up and express the divinity within you.


Green house effect is a very dangerous issue of the world. It now threatens human survival and existence with various natural disasters. It is mainly caused by global warming. Various factors like carbon dioxide, industrial waste, environment and water pollution are responsible for this. The poor countries are its worst victims. Its more devastating effect now concerns the whole world.

Greenhouse is originally related to  the developed cold countries where is an insufficiency of sunrays. Here people make special houses of glass to grow plant and vegetables. The sunlight can easily enter these houses but can not get out easily. So the inside air grows hotter and hotter. Carbon dioxide, CFC and  methane contribute to the heat. Same is the case with the present world. Some significant reasons of the greenhouse effect are the burning down of tropical rain forests, traffic jams of the cities, rapid growth of industries etc. The pollution of different elements of environment like air, water  and soil is also responsible for it. All these factors cause the trapping of heat in the air of our atmosphere. Naturally, it is followed by global warming increasing gradually. This increase has already reached a dangerous level with some dangerous symptoms like hostile natural behavior. It is called greenhouse effect.
Whatever may be the reason the result of greenhouse effect is very catastrophic. Firstly, the temperature of the earth is increasing alarmingly. This reduces mankind’s ability of produce food, severely damages the wild life and wilderness. National disasters like floods take place due to the melting of polar ice.  It has also brought a significant change in our world’s climate followed by environmental catastrophes. Naturally, our total eco-system, with its biosphere, is at stake. Besides, frequent natural disasters like earthquakes, cyclones, floods etc. have turned the total situation from bad to worse.

It is our duty to protect the environment from being polluted. The industrially developed countries must tale effective measures to control the emission of green house gases so that the environment does not get polluted alarmingly. Our safe existence depends on the safety of the moment. This safety can be ensured by concerted efforts of both the rich and poor countries. Until the developed countries cannot avoid their responsibility of this pollution through – sive emotion of harmful gases. 

Cyclone is a natural calamity. It occurs in Bangladesh very frequently.
Cyclone is a violent storm. At times air goes up due to excessive heat. Then a vacum is created in the air. As a result air from nearby places rushes to fill the vacuum. Such whirling of air is called cyclone.
A cyclone may occur at any time and at any place. It mostly occurs within the tropics. Usually it has origin on the sea owing to low pressure of atmosphere. Then it begins to blow violently towards the land. It is often accompanied by thunders and heavy showers. Thunder roars and lightning flashes. Nature looks gloomy and terrible.
A cyclone lasts for a few minutes only, sometimes for hours. It causes great havoc to the areas of its visit. It uproots trees, blows away houses, smashes buildings and kills men and cattle. It sinks boats, ships and launches. It also causes tidal waves.
A terrible cyclone accompanied by tidal bore swept over some coastal districts of Bangladesh on the 29th April,1991. It swept at a speed of 235 kilometres per hour. It lasted for the whole night and caused much ruin. Thousands and thousands of houses were leveled to the ground. Trees were felled and uprooted. Lands of Hatiya, Sandwip, Urirchar, Chittangong, Cox’s bazaar, Kutubdia, Moheshkhali, Bhola etc. went under water. Crops were damaged. Ships, boats and launches sank. About 1 lakh 39 thousand of human lives and thousands of cattle were killed.
Government with the assistance of the people of Bangladesh took prompt measures for the relief, rescue and rehabilitation of the affected persons. Foreign nations and international organizations also came up with necessary help.
We have no control over such a natural calamity. The government may, however, take pre-caution and warn the people to take shelter in safer places
