Gita Chapter 18.31 to 18.35

Yayaa dharmamadharmam cha kaaryam chaakaaryameva cha;
Ayathaavat prajaanaati buddhih saa paartha raajasee.
31. That by which one incorrectly understands Dharma and Adharma, and also what ought to be done and what ought not to be done—that intellect, O Arjuna, is Rajasic!
COMMENTARY: That which is ordained in the scriptures is Dharma. That which hurls you into the abyss of ignorance is Adharma. The Rajasic intellect is not able to distinguish between righteous and unrighteous actions.

Adharmam dharmamiti yaa manyate tamasaavritaa;
Sarvaarthaan vipareetaamshcha buddhih saa paartha taamasee.
32. That which, enveloped in darkness, views Adharma as Dharma and all things perverted—that intellect, O Arjuna, is called Tamasic!

Dhrityaa yayaa dhaarayate manah praanendriyakriyaah;
Yogenaavyabhichaarinyaa dhritih saa paartha saattwikee.
33. The unwavering firmness by which, through Yoga, the functions of the mind, the life-force and the senses are restrained—that firmness, O Arjuna, is Sattwic!

Yayaa tu dharmakaamaarthaan dhrityaa dhaarayate’rjuna;
Prasangena phalaakaangkshee dhritih saa paartha raajasee.
34. But that firmness, O Arjuna, by which, on account of attachment and desire for reward, one holds fast to Dharma, enjoyment of pleasures and earning of wealth—that firmness, O Arjuna, is Rajasic!

Yayaa swapnam bhayam shokam vishaadam madameva cha;
Na vimunchati durmedhaa dhritih saa paartha taamasee.
35. That by which a stupid man does not abandon sleep, fear, grief, despair and also conceit—that firmness, O Arjuna, is Tamasic!

Gita Chapter 7.11 to 7.15

Balam balavataam asmi kaamaraagavivarjitam;
Dharmaaviruddho bhooteshu kaamo’smi bharatarshabha.
11. Of the strong, I am the strength devoid of desire and attachment, and in (all) beings, I am the desire unopposed to Dharma, O Arjuna!

Ye chaiva saattvikaa bhaavaa raajasaastaamasaashcha ye;
Matta eveti taanviddhi na twaham teshu te mayi.
12. Whatever being (and objects) that are pure, active and inert, know that they proceed from Me. They are in Me, yet I am not in them.

Tribhirgunamayair bhaavairebhih sarvamidam jagat;
Mohitam naabhijaanaati maamebhyah paramavyayam.
13. Deluded by these Natures (states or things) composed of the three qualities of Nature, all this world does not know Me as distinct from them and immutable.

Daivee hyeshaa gunamayee mama maayaa duratyayaa;
Maameva ye prapadyante maayaametaam taranti te.
14. Verily this divine illusion of Mine made up of the qualities (of Nature) is difficult to cross over; those who take refuge in Me alone cross over this illusion.

Na maam dushkritino moodhaah prapadyante naraadhamaah;
Maayayaapahritajnaanaa aasuram bhaavamaashritaah.
15. The evil-doers and the deluded, who are the lowest of men, do not seek Me; they whose knowledge is destroyed by illusion follow the ways of demons.
