An excerpt from Bhagavad Gita

Look to this day,
For it is life,
The very life of life.
In its brief course lie all the varieties
And realities of your existence;
The bliss of growths 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 salvation of the dawn.
