"Once the Buddha was asked to explain real happiness

"Once the Buddha was asked to explain real happiness. He enumerated various wholesome actions which are productive of happiness, which are real blessings. All these blessings fall into two categories: performing actions that contribute to the welfare of others by fulfilling responsibilities to family and society, and performing actions that cleanse the mind. One's own good is inextricable from the good of others. And at last he said,

"When faced with all the ups and downs of life,

still the mind remains unshaken,

not lamenting, not generating defilements, 

always feeling secure; this is the greatest happiness."

[Mahā-Mangala Sutta]

"No matter what arises, whether within the microcosm of one's own mind and body or in the world outside, one is able to face it — not with tension, with barely suppressed craving and aversion—but with complete ease, with a smile that comes from the depths of the mind. In every situation, pleasant or unpleasant, wanted or unwanted, one has no anxiety, one feels totally secure, secure in the understanding of impermanence. This is the greatest blessing."
