Although the meaning of religion may vary from person to person, all religions generally profess to have sublime teaching. Great religions clearly acknowledge and understand the value of human life and guide humanity accordingly.In the 21st century, many desire a clear roadmap based on the tenets of logic and science for their transformation from suffering to happiness and freedom-the universal desire of human beings. Buddhism teaches that happiness and freedom are possible when one possesses the wisdom to see oneself and the world correctly. Wholesome minds cultivate a wholesome culture; unwholesome minds contribute to an unwholesome culture. A wholesome mind is thoughtful and selfless; an unwholesome mind is self-centered and produces the three poisons known as "lust∙hatred∙delusion."Two thousand six hundred years ago, the Gautama Buddha attained Nibbāna. He said we all could achieve ordinary and ultimate happiness-Nibbāna-through the Four Noble Truths and the Noble Eightfold Path.
