The Bhagavad Gita
The excerpt from the chapter 3, Karma Yoga – Yoga of Action
Arjuna asked: My Lord! Tell me, what is it that drives a man to sin, even against his will and as if by compulsion?
Lord Shri Krishna: It is desire, it is aversion, born of passion. Desire consumes and corrupts everything. It is man’s greatest enemy.
As fire is shrouded in smoke, a mirror by dust and a child by the womb, so is the universe enveloped in desire.
It is the wise man’s constant enemy; it tarnishes the face of wisdom. It is as insatiable as a flame of fire.
It works through the senses, the mind and the reason; and with their help destroys wisdom and confounds the soul.
Therefore, O Arjuna, first control thy senses and then slay desire, for it is full of sin, and is the destroyer of knowledge and of wisdom.
It is said that the senses are powerful. But beyond the senses is the mind, beyond the mind is the intellect, and beyond and greater than intellect is He.
Thus, O Mighty-in-Arms, knowing Him to be beyond the intellect and, by His help,subduing thy personal egotism, kill thine enemy, Desire, extremely difficult though it be.
The excerpt from the chapter 2 where Krishna summarized his teaching.
Arjuna asked: My Lord! How can we recognise the saint who has attained Pure Intellect, who has reached this state of Bliss, and whose mind is steady? how does he talk, how does he live, and how does he act?
Lord Shri Krishna replied: When a man has given up the desires of his heart and is satisfied with the Self alone, be sure that he has reached the highest state. The sage, whose mind is unruffled in suffering, whose desire is not roused by enjoyment, who is without attachment, anger or fear – take him to be one who stands at that lofty level.
He who wherever he goes is attached to no person and to no place by ties of flesh; who accepts good and evil alike, neither welcoming the one nor shrinking from the other – take him to be one who is merged in the Infinite.
He who can withdraw his senses from the attraction of their objects, as the tortoise draws his limbs within its shell – take it that such a one has attained Perfection. The objects of sense turn from him who is abstemious. Even the relish for them is lost in him who has seen the Truth.
O Arjuna! The mind of him, who is trying to conquer it, is forcibly carried away in spite of his efforts, by his tumultuous senses.
Restraining them all, let him meditate steadfastly on Me; for who thus conquers his senses achieves perfection.
When a man dwells on the objects of sense, he creates an attraction for them; attraction develops into desire, and desire breeds anger.
Anger induces delusion; delusion, loss of memory; through loss of memory, reason is shattered; and loss of reason leads to destruction.
But the self-controlled soul, who moves amongst sense objects, free from either attachment or repulsion, he wins eternal Peace.
Having attained Peace, he becomes free from misery; for when the mind gains peace, right discrimination follows.
Right discrimination is not for him who cannot concentrate. Without concentration, there cannot be meditation; he who cannot meditate must not expect peace; and without peace, how can anyone expect happiness?
As a ship at sea is tossed by the tempest, so the reason is carried away by the mind when preyed upon by straying senses.
Therefore, O Might-in-Arms, he who keeps his senses detached from their objects – take it that his reason is purified.
The saint is awake when the world sleeps, and he ignores that for which the world lives.
He attains Peace, into whom desires flow as rivers into the ocean, which though brimming with water remains ever the same; not he whom desire carries away.
He attains Peace who, giving up desire, moves through the world without aspiration, possessing nothing which he can call his own, and free from pride.
O Arjuna! This is the state of the Self, the Supreme Spirit, to which if a man once attain, it shall never be taken from him. Even at the time of leaving the body, he will remain firmly enthroned there, and will become one with the Eternal.
