here's my take on bliss:

Hugging one of your children
looking into the eyes of a new-born baby,
an orgasm with the one you love, (including foreplay)
christmas dinner with your family,
watching a sunset over the sea,
catching a big seabass,
a curry in Southall with some friends,
the scent of a rose,
swimming in a warm sea on a hot day,
seeing the Trashcan Sinatras play live,
your dad coming home from the war in one piece.

etc

Who cares if it's all transient, so am I.
