My mom shared these with me today:
Buddha: “Do not dwell in the past, do not dream in the future, concentrate the mind in the present moment.”
“Time is an unwholesome physician, for it deceives the patient daily with the expectation of the future, and before expelling the old pain, it adds new ones to the old and accumulates daily so many evils that through the fallacious hope of life it leads to death. We must live today: he who lives tomorrow never lives. (Ficino, cited in Kristeller, 1943: 295)
in poetry, as in Longfellow’s A Psalm of Life
Trust no future, howe’ver pleasant!
Let the dead Past bury its dead!
Act, – act in the living present!
“Only in the present is our happiness”. The goal of these “therapies” was to allow people to free themselves from the past and the future, so that they could live within the present. Hadot (1995: 69)
And now one of my favorites (which doesn’t quite fit, but somehow seems appropriate):
