Look to this day,A selection from The Bhagavad Gita. Also attributed to the Indian poet Kalidasa.
For it is life,
The very life of life.
In its brief course lie all the truths
And realities of your existence;
The bliss of growth
The glory of action,
The splendor of beauty;
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.
Such is the salutation of the dawn.
