The Four Noble Truths
First Noble Truth
Life is suffering. But by living a mindful existence we can learn to avoid suffering and achieve true happiness.
Second Noble Truth
Suffering is caused by craving and aversion. Rather than struggling to achieve everything we want, we should modify our wanting. Wanting deprives us of true happiness and contentment.
Third Noble Truth
Suffering can be overcome and happiness can be attained. True happiness is possible. If we give up useless craving and learn to live each day at a time (not dwelling in the past or worrying about the future) then we can become happy and free. We then have more time and energy to help others. This is Nirvana.
Fourth Noble Truth
Nirvana can be achieved by perfecting our understanding of the world, acting out of true love and compassion, using only true, uplifting, non-harmful communication, acting in an ethical manner, living a life which does not exploit others, consciously working to better ourselves, developing complete awareness of ourselves and the world around us, and by developing not only complete consciousness and awareness in mind, but in being.
