Sanskrit Proverb

Look to this day
This very life of life
In its brief course lie all
The realities and verities of existence
The bliss of growth
The splendour of action
the glory of power—

For yesterday is but a dream
And tomorrow is only 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
