Kalidasa says:

“Look to this day,

for it is life, the very breath of life.

In its brief course lie

all the realities of your existence;

the bliss of growth,

the glory of action,

the splendor of beauty.

For yesterday is only a dream,

and tomorrow is but a vision.

But today, well lived,

makes every yesterday a dream of happiness,

and every tomorrow

a vision of hope. Look well therefore, to this day.”

Kalidasa : Indian Poet and playwright, active in the 4th and 5th century AD.
