Gita Chapter 16.16 to 16.20

Anekachittavibhraantaah mohajaalasamaavritaah;
Prasaktaah kaamabhogeshu patanti narake’shuchau.
16. Bewildered by many a fancy, entangled in the snare of delusion, addicted to the gratification of lust, they fall into a foul hell.

Aatmasambhaavitaah stabdhaa dhanamaanamadaanvitaah;
Yajante naamayajnaiste dambhenaavidhipoorvakam.
17. Self-conceited, stubborn, filled with the intoxication and pride of wealth, they perform sacrifices in name, through ostentation, contrary to scriptural ordinances.

Ahankaaram balam darpam kaamam krodham cha samshritaah;
Maamaatmaparadeheshu pradwishanto’bhyasooyakaah.
18. Given over to egoism, power, haughtiness, lust and anger, these malicious people hate Me in their own bodies and those of others.

Taanaham dwishatah krooraan samsaareshu naraadhamaan;
Kshipaamyajasram ashubhaan aasureeshweva yonishu.
19. These cruel haters, the worst among men in the world,—I hurl all these evil-doers for ever into the wombs of demons only.

Aasureem yonimaapannaa moodhaa janmani janmani;
Maamapraapyaiva kaunteya tato yaantyadhamaam gatim.
20. Entering into demoniacal wombs and deluded birth after birth, not attaining Me, they thus fall, O Arjuna, into a condition still lower than that!

Gita Chapter 2.41to 2.45

Vyavasaayaatmikaa buddhir ekeha kurunandana;
Bahushaakhaa hyanantaashcha buddhayo’vyavasaayinaam.
41. Here, O joy of the Kurus, there is a single one-pointed determination! Many-branched and endless are the thoughts of the irresolute.

Yaam imaam pushpitaam vaacham pravadantyavipashchitah;
Vedavaadarataah paartha naanyad asteeti vaadinah.
42. Flowery speech is uttered by the unwise, who take pleasure in the eulogising words of the Vedas, O Arjuna, saying: “There is nothing else!”
COMMENTARY: Unwise people who lack discrimination place great stress upon the Karma Kanda or ritualistic portion of the Vedas which lays down specific rules for specific actions for the attainment of specific fruit. They extol these actions and rewards unduly.

Kaamaatmaanah swargaparaa janmakarmaphalapradaam;
Kriyaavisheshabahulaam bhogaishwaryagatim prati.
43. Full of desires, having heaven as their goal, they utter speech which promises birth as the reward of one’s actions, and prescribe various specific actions for the attainment of pleasure and power.

Bhogaishwarya prasaktaanaam tayaapahritachetasaam;
Vyavasaayaatmikaa buddhih samaadhau na vidheeyate.
44. For those who are much attached to pleasure and to power, whose minds are drawn away by such teaching, that determinate faculty is not manifest that is steadily bent on meditation and Samadhi (the state of Superconsciousness).

Traigunyavishayaa vedaa nistraigunyo bhavaarjuna;
Nirdwandwo nityasatwastho niryogakshema aatmavaan.
45. The Vedas deal with the three attributes (of Nature); be thou above these three attributes, O Arjuna! Free yourself from the pairs of opposites and ever remain in the quality of Sattwa (goodness), freed from the thought of acquisition and preservation, and be established in the Self.
COMMENTARY: Guna means attribute or quality. It is substance as well as quality. Nature is made up of three Gunas—Sattwa (purity, light, harmony), Rajas (passion, restlessness, motion), and Tamas (inertia, darkness). The pairs of opposites are pleasure and pain, heat and cold, gain and loss, victory and defeat, honour and dishonour, praise and censure.
