"He instructed Arjuna, and said many wise things. I will tell you some of them, here and there, as they are scattered through the holy _Bhagavad-Gitá_: Then between the two armies, Krishna, smiling, addressed these words to him, thus downcast:
"'Thou hast grieved for those who need not be grieved for, yet thou utterest words of wisdom. The wise grieve not for dead or living. But never at any period did I or thou or these kings of men not exist, nor shall any of us at any time henceforward cease to exist. There is no existence for what does not exist, nor is there any non-existence for what exists.... These finite bodies have been said to belong to an eternal, indestructible and infinite spirit.... He who believes that this spirit can kill, and he who thinks that it can be killed--both of these are mistaken. It neither kills nor is killed. It is born, and it does not die.... Unborn, changeless, eternal both as to future and past time, it is not slain when the body is killed.... As the soul in this body undergoes the changes of childhood, prime and age, so it obtains a new body hereafter.... As a man abandons worn-out clothes and take other new ones, so does the soul quit worn-out bodies and enter other new ones. Weapons cannot cleave it, fire cannot burn it, nor can water wet it, nor can wind dry it. It is impenetrable, incombustible, incapable of moistening and of drying. It is constant; it can go everywhere; it is firm, immovable and eternal. And even if thou deem it born with the body and dying with the body, still, O great-armed one! thou art not right to grieve for it. For to everything generated death is certain: to everything dead regeneration is certain.... One looks on the soul as a miracle; another speaks of it as a miracle; another hears of it as a miracle; but even when he has heard of it, not one comprehends it.... When a man's heart is disposed in accordance with his roaming senses, it snatches away his spiritual knowledge as the wind does a ship on the waves.... He who does not practice devotion has neither intelligence nor reflection. And he who does not practice reflection has no calm. How can a man without calm obtain happiness? The self-governed man is awake in that which is night to all other beings: that in which other beings are awake is night to the self-governed. He into whom all desires enter in the same manner as rivers enter the ocean, which is always full, yet does not change its bed, can obtain tranquillity.... Love or hate exists toward the object of each sense. One should not fall into the power of these two passions, for they are one's adversaries.... Know that passion is hostile to man in this world. As fire is surrounded by smoke, and a mirror by rust, and a child by the womb, so is this universe surrounded by passion.... They say that the senses are great. The heart is greater than the senses. But the intellect is greater than the heart, and passion is greater than the intellect....
