Guru Nanak was born 550 years ago, yet his life and teachings still hold great power and meaning for humanity. He not only propounded a new way of life but a realistic and optimistic worldview. His teachings focus on the upliftment of the weaker sections of society and their empowerment to live a life of dignity. Love of God, egalitarianism, altruism, lifelong learning, Interdependence, impermanence, harmony with nature, cultivation of scientific temper, freedom, and justice for all are the lodestars of (...) Guru Nanak’s message to humanity. Three cardinal points of his teachings: Kirat Karo (honest living), Naam Japo (devotion to God), and Vand Chhako (sharing with others) have become an integral part of the lives of Sikhs all over the world. His teachings found expression in the establishment of various institutions e.g. dharamsals (gurdwaras) and the development of langar (community kitchen), pangat (sitting in a row on the same level), and Sangat (holy congregation) traditions among his followers.

All the biotic and abiotic factors that act on an organism, population, or ecological community and influence its survival and development constitute its environment. Biotic factors include the organisms themselves, their food, and their interactions. Abiotic factors include such items as sunlight, soil, air, water, climate, and pollution. Organisms respond to changes in their environment by evolutionary adaptations in form and behaviour. At present humanity is facing great challenges for its survival as both these factors have come under great stress (...) due to its unbridled demands of national economic growth and individual needs and desires. Grave Crisis: On the abiotic front, a grave ecological crisis is caused by man’s exploitation of Nature, which is leading to a large scale depletion of natural resources, destruction of forests, and overuse of land for agriculture and habitation. Pollution is contaminating air, land, and water. Smoke from industries, homes and vehicles, is in the air. A smoky haze envelopes the major cities of the world. Industrial waste and consumer trash are choking streams and rivers, ponds and lakes, killing the marine life. Much of the waste is a product of modern technology. It is neither biodegradable nor reusable, and its longterm consequences are unknown. The viability of many animal and plant species, and possibly that of the humankind itself, is at stake. At the biotic level, humanity is facing a social justice crisis, which is caused by humanity’s confrontation with itself. The social justice crisis is that poverty, hunger, disease, exploitation and injustice are widespread. There are economic wars over resources and markets. The rights of the poor and the marginal are violated. Women, constituting half the world’s population, have their rights abused. Obviously, the contemporary human society is in the midst of a grave environmental crisis. There is a serious concern that the earth may no longer be a sustainable biosystem. Although human beings are seen as the most intelligent life form on earth, yet they are responsible for almost all the ecological damage done to the planet. The Sikh scripture, Sri Guru Granth Sahib (SGGS), declares that the purpose of human beings is to achieve a blissful state and to be in harmony with the earth and all of God’s creation. It seems, however, that humans have drifted away from that ideal. According to the Sikh scriptures, humans create their surroundings as a reflection of their inner state. Thus, the increasing barrenness of the earth reflects a spiritual emptiness within humans. (shrink)
