We all experience the happy moments and the sad moments in life. And we continually strive for happiness - ever lasting happiness because that is the true nature of our consciousness – Sat-Chit-Anand (Eternal-Conscious-Blissfull). The sages of the east did a lot of self analysis and broadly categorized five flavors of happiness.
Every living being live, enjoys and chase the happiness associated with sensual pleasures. The wise men also called such happiness as the “Vishay-Sukh” or the material happiness. Such happiness is related with the five senses and their associated subjects: tongue experiences the delicious taste; eyes observe the beauty; ears hear the melodious sound; nose smells the fragrance; and the sensual pleasures of the touch of body with the opposite sex. I don't have to describe these pleasures in detail. Even animals experience such kind of natural happiness. We all experiences these pleasure in daily life and crave for these pleasures throughout our lives. But at the same time, we never get satisfied with it.
