Life without death and happiness without misery are contradiction and neither can be found alone, because each of them is a different manifestation of the same thing.
Happiness is one pole, sadness is another. Blissfulness is one pole, misery is another. Life consists of both, and life is richer because of both. A life only of blissfulness will have extension, but will not have depth. A life of only sadness will have depth, but will not have extension.
Imagine every day to he 5 the last6 of a life surrounded with hopes, cares, anger, and fear. The hours, that come unexpectedly, will be so much the more grateful.
Each thing tends to move towards its own nature. I always desire happiness which is my true nature. My nature is never a burden to me. Happiness is never a burden to me, whilst sorrow is.
Even if only a few individuals try to create mental peace and happiness within themselves, and act responsibly and kind-heartedly towards others, they will have a positive influence in their community.
