Definition of "bliss"

Bliss was it in that dawn to be alive, / But to be young was very heaven!

a. 1851, William Wordsworth, “The French Revolution as It Appeared to Enthusiasts at Its Commencement”, in Henry [Hope] Reed, editor, The Complete Poetical Works of William Wordsworth, Philadelphia, Pa.: Hayes & Zell, […], published 1860, page 188

What can you do if you are thirty and, turning the corner of your own street, you are overcome, suddenly, by a feeling of bliss—absolute bliss!—as though you'd suddenly swallowed a bright piece of that late afternoon sun and it burned in your bosom, sending out a little shower of sparks into every particle, into every finger and toe?

1918 August, Katherine Mansfield [pseudonym; Kathleen Mansfield Murry], “Bliss”, in Bliss and Other Stories, London: Constable & Company, published 1920, page 116
