The life span of human beings is one hundred years. Half of it is spent as nights ( in sleeping). Half of the remaining (25 years) is spent in childhood and old age and the remaining 25 years are spent in fighting diseases, separation, miseries and service, Further, the expectancy of life is extremely unstable like the waves generated in water. So where is the happiness in the life of all living beings ?
Happiness relies on how good you manage each 25 years Ashram. How earnest your efforts are in pursuing 4 puruShArtha(s) i.e. Dharma, Artha, Kama, Moksha.
Re-align your life around 4 P and experience the happiness.
