Chapter 6, Verse 5.
A man must elevate himself by his own mind, not degrade himself. The mind is the friend of the conditioned soul, and his enemy as well.
Chapter 6, Verse 6.
For him who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his very mind will be the greatest enemy.
Chapter 6, Verse 7.
For one who has conquered the mind, the Supersoul is already reached, for he has attained tranquility. To such a man happiness and distress, heat and cold, honor and dishonor are all the same.
Chapter 6, Verse 8.
A person is said to be established in self-realization and is called a yogi [or mystic] when he is fully satisfied by virtue of acquired knowledge and realization. Such a person is situated in transcendence and is self-controlled. He sees everything--whether it be pebbles, stones or gold--as the same.
Chapter 6, Verse 9.
A person is said to be still further advanced when he regards all--the honest well-wisher, friends and enemies, the envious, the pious, the sinner and those who are indifferent and impartial--with an equal mind.
Chapter 6, Verse 29.
A true yogi observes Me in all beings, and also sees every being in Me. Indeed, the self-realized man sees Me everywhere.
Chapter 6, Verse 30.
For one who sees Me everywhere and sees everything in Me, I am never lost, nor is he ever lost to Me.
Chapter 6, Verse 31.
The yogi who knows that I and the Supersoul within all creatures are one worships Me and remains always in Me in all circumstances.
Chapter 6, Verse 32.
He is a perfect yogi who, by comparison to his own self, sees the true equality of all beings, both in their happiness and distress, O Arjuna!
Chapter 6, Verse 33.
Arjuna said: O Madhusudana, the system of yoga which You have summarized appears impractical and unendurable to me, for the mind is restless and unsteady.
Chapter 6, Verse 34.
For the mind is restless, turbulent, obstinate and very strong, O Krsna, and to subdue it is, it seems to me, more difficult than controlling the wind.
Chapter 6, Verse 35.
The Blessed Lord said: O mighty-armed son of Kunti, it is undoubtedly very difficult to curb the restless mind, but it is possible by constant practice and by detachment.
Chapter 6, Verse 36.
For one whose mind is unbridled, self-realization is difficult work. But he whose mind is controlled and who strives by right means is assured of success. That is My opinion.Bhagavad Gita, Chapter 6: Sankhya-yoga( Collapse )
