Sanskrit Proverb For Serenity And Peace

Look to this day,
The very life of life,
In its brief course lies all
The realities and varieties of existence,
The bliss of growth,
The splendor 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.
