Bhagavad-Gita

http://www.bhagavad-gita.org/index-english.html

(Sri Krishna to Arjuna the warrior, who is disinclined to fight):

  Your words are wise, Arjuna, but your sorrow is for nothing.
  The truly wise mourn neither for the living nor for the dead.

  There never was a time when I did not exist, not you, nor any
  of these kings. Nor is there any future in which we shall cease
  to be.

  Just as the dweller in this body passes through childhood, youth
  and old age, so at death he merely passes into another kind of
  body. The wise are not deceived by that.

  Feelings of heat and cold, pleasure and pain, are caused by the
  contact of the senses with their objects.  They come and they
  go, never lasting long.  You must accept them.

  A serene spirit accepts pleasure and pain with an even mind, and
  is unmoved by either.  He alone is worthy of immortality.

  That which is non-existent can never come into being, and that
  which is can never cease to be.  Those who have known the inmost
  Reality know also the nature of *is* and *is not*.

  That Reality which pervades the universe is indestructible.  No
  one has power to change the Changeless.

  Bodies are said to die, but That which possesses the body is
  eternal.  It cannot be limited, or destroyed.  Therefore you
  must fight.
BHA-01

                           ARJUNA:

Krishna, how can one identify a man who is firmly
established and absorbed in Brahman?

                       SRI  KRISHNA:

He knows bliss in the Atman
And wants nothing else.
Craving torments the heart:
He renounces cravings.
I call him illumined.

Not shaken by adversity,
Not hankering after happiness:
Free from fear, free from anger,
Free from the things of desire.
I call him a seer, and illumined.

The bonds of his flesh are broken.
He is lucky, and does not rejoice:
He is unlucky, and does not weep.
I call him illumined.

The tortoise can draw in his legs:
The seer can draw in his senses.
I call him illumined.

The abstinent run away from what they desire
But carry their desires with them:
When a man enters Reality,
He leaves his desires behind him.

Even a mind that knows the path
Can be dragged from the path:
The senses are so unruly.
But he controls the senses
And recollects the mind
And fixes it on me.
I call him illumined.

Thinking about sense objects
Will attach you to sense objects;
Grow attached, and you become addicted;
Thwart your addiction, it turns into anger;
Be angry, and you confuse your mind;
Confuse your mind, you forget the lesson of experience;
Forget experience, you lose discrimination;
Lose discrimination, and you miss life's only purpose.

When he has no lust, no hatred,
A man walks safely among the things of lust and hatred.
To obey the Atman
Is his peaceful joy:
Sorrow melts
Into that clear peace:
His quiet mind
Is soon established in peace.
