Gita Chapter 18.36 to 18.40

Sukham twidaaneem trividham shrinu me bharatarshabha;
Abhyaasaadramate yatra duhkhaantam cha nigacchati.
36. Now hear from Me, O Arjuna, of the threefold pleasure, in which one rejoices by practice and surely comes to the end of pain!

Yattadagre vishamiva parinaame’mritopamam;
Tatsukham saattwikam proktam aatmabuddhiprasaadajam.
37. That which is like poison at first but in the end like nectar—that pleasure is declared to be Sattwic, born of the purity of one’s own mind due to Self-realisation.

Vishayendriya samyogaad yattadagre’mritopamam;
Parinaame vishamiva tatsukham raajasam smritam.
38. That pleasure which arises from the contact of the sense-organs with the objects, which is at first like nectar and in the end like poison—that is declared to be Rajasic.

Yadagre chaanubandhe cha sukham mohanamaatmanah;
Nidraalasyapramaadottham tattaamasamudaahritam.
39. That pleasure which at first and in the sequel is delusive of the self, arising from sleep, indolence and heedlessness—such a pleasure is declared to be Tamasic.

Na tadasti prithivyaam vaa divi deveshu vaa punah;
Sattwam prakritijairmuktam yadebhih syaat tribhirgunaih.
40. There is no being on earth or again in heaven among the gods that is liberated from the three qualities born of Nature.

Gita Chapter 6.31 to 6.35

Sarvabhootasthitam yo maam bhajatyekatwamaasthitah;
Sarvathaa vartamaano’pi sa yogee mayi vartate.
31. He who, being established in unity, worships Me who dwells in all beings,—that Yogi abides in Me, whatever may be his mode of living.

Aatmaupamyena sarvatra samam pashyati yo’rjuna;
Sukham vaa yadi vaa duhkham sa yogee paramo matah.
32. He who, through the likeness of the Self, O Arjuna, sees equality everywhere, be it pleasure or pain, he is regarded as the highest Yogi!

Arjuna Uvaacha:
Yo’yam yogastwayaa proktah saamyena madhusoodana;
Etasyaaham na pashyaami chanchalatwaat sthitim sthiraam.
Arjuna said:
33. This Yoga of equanimity taught by Thee, O Krishna, I do not see its steady continuance, because of restlessness (of the mind)!

Chanchalam hi manah krishna pramaathi balavad dridham;
Tasyaaham nigraham manye vaayoriva sudushkaram.
34. The mind verily is restless, turbulent, strong and unyielding, O Krishna! I deem it as difficult to control as to control the wind.
COMMENTARY: The mind ever changes its point of concentration from one object to another. So it is always restless. It is not only restless but also turbulent and impetuous, strong and obstinate. It produces agitation in the body and in the senses. That is why the mind is even more difficult to control than to control the wind.

Sri Bhagavaan Uvaacha:
Asamshayam mahaabaaho mano durnigraham chalam;
Abhyaasena tu kaunteya vairaagyena cha grihyate.
The Blessed Lord said:
35. Undoubtedly, O mighty-armed Arjuna, the mind is difficult to control and restless; but, by practice and by dispassion it may be restrained!

Gita Chapter 6.11 to 6.15

Shuchau deshe pratishthaapya sthiramaasanamaatmanah;
Naatyucchritam naatineecham chailaajinakushottaram.
11. In a clean spot, having established a firm seat of his own, neither too high nor too low, made of a cloth, a skin and kusha grass, one over the other,

Tatraikaagram manah kritwaa yatachittendriyakriyah;
Upavishyaasane yunjyaadyogamaatmavishuddhaye.
12. There, having made the mind one-pointed, with the actions of the mind and the senses controlled, let him, seated on the seat, practise Yoga for the purification of the self.

Samam kaayashirogreevam dhaarayannachalam sthirah;
Samprekshya naasikaagram swam dishashchaanavalokayan.
13. Let him firmly hold his body, head and neck erect and perfectly still, gazing at the tip of his nose, without looking around.

Prashaantaatmaa vigatabheer brahmachaarivrate sthitah;
Manah samyamya macchitto yukta aaseeta matparah.
14. Serene-minded, fearless, firm in the vow of a Brahmachari, having controlled the mind, thinking of Me and balanced in mind, let him sit, having Me as his supreme goal.

Yunjannevam sadaa’tmaanam yogee niyatamaanasah;
Shaantim nirvaanaparamaam matsamsthaamadhigacchati.
15. Thus, always keeping the mind balanced, the Yogi, with the mind controlled, attains to the peace abiding in Me, which culminates in liberation.

Gita Chapter 3.31 to 3.35

Ye me matam idam nityam anutishthanti maanavaah;
Shraddhaavanto’nasooyanto muchyante te’pi karmabhih.
31. Those men who constantly practise this teaching of Mine with faith and without cavilling, they too are freed from actions.

Ye twetad abhyasooyanto naanutishthanti me matam;
Sarvajnaanavimoodhaam staan viddhi nashtaan achetasah.
32. But those who carp at My teaching and do not practise it, deluded in all knowledge and devoid of discrimination, know them to be doomed to destruction.

Sadrisham cheshtate swasyaah prakriter jnaanavaan api;
Prakritim yaanti bhootaani nigrahah kim karishyati.
33. Even a wise man acts in accordance with his own nature; beings will follow nature; what can restraint do?
COMMENTARY: Only the ignorant man comes under the sway of his natural propensities. The seeker after Truth who is endowed with the ‘Four Means’ and who constantly practises meditation, can easily control Nature if he rises above the sway of the pairs of opposites, like love and hate, etc.

Indriyasyendriyasyaarthe raagadweshau vyavasthitau;
Tayor na vasham aagacchet tau hyasya paripanthinau.
34. Attachment and aversion for the objects of the senses abide in the senses; let none come under their sway, for they are his foes.

Shreyaan swadharmo vigunah paradharmaat swanushthitaat;
Swadharme nidhanam shreyah paradharmo bhayaavahah.
35. Better is one’s own duty, though devoid of merit, than the duty of another well discharged. Better is death in one’s own duty; the duty of another is fraught with fear.
