Gita Chapter 17.21 to 17.25

Yattu pratyupakaaraartham phalamuddishya vaa punah;
Deeyate cha pariklishtam taddaanam raajasam smritam.
21. And, that gift which is made with a view to receive something in return, or looking for a reward, or given reluctantly, is said to be Rajasic.

Adeshakaale yaddaanamapaatrebhyashcha deeyate;
Asatkritamavajnaatam tattaamasamudaahritam.
22. The gift which is given at the wrong place and time to unworthy persons, without respect or with insult, is declared to be Tamasic.
COMMENTARY: At the wrong place and time—at a place which is not holy, where irreligious people and beggars assemble, where wealth acquired through illegal means such as gambling and theft, is distributed to gamblers, singers, fools, rogues, women of evil reputation; wealth that is distributed at an inauspicious time. This does not discourage the giving of alms to the poor.

Om tatsaditi nirdesho brahmanas trividhah smritah;
Braahmanaastena vedaashcha yajnaashcha vihitaah puraa.
23. “Om Tat Sat”: this has been declared to be the triple designation of Brahman. By that were created formerly the Brahmanas, the Vedas and the sacrifices.

Tasmaadomityudaahritya yajnadaanatapahkriyaah;
Pravartante vidhaanoktaah satatam brahmavaadinaam.
24. Therefore, with the utterance of “Om” are the acts of gift, sacrifice and austerity as enjoined in the scriptures always begun by the students of Brahman.

Tadityanabhisandhaaya phalam yajnatapah kriyaah;
Daanakriyaashcha vividhaah kriyante mokshakaangkshibhih.
25. Uttering Tat, without aiming at the fruits, are the acts of sacrifice and austerity and the various acts of gift performed by the seekers of liberation.

Gita Chapter 9.11 to 9.15

Avajaananti maam moodhaah maanusheem tanumaashritam;
Param bhaavamajaananto mama bhootamaheshwaram.
11. Fools disregard Me, clad in human form, not knowing My higher Being as the great Lord of (all) beings.
COMMENTARY: Fools who do not have discrimination despise Me, dwelling in human form. I have taken this body in order to bless My devotees. These fools have no knowledge of My higher Being. I am the great Lord, the Supreme.

Moghaashaa moghakarmaano moghajnaanaa vichetasah;
Raakshaseemaasureem chaiva prakritim mohineem shritaah.
12. Of vain hopes, of vain actions, of vain knowledge and senseless, they verily are possessed of the deceitful nature of demons and undivine beings.

Mahaatmaanastu maam paartha daiveem prakritimaashritaah;
Bhajantyananyamanaso jnaatwaa bhootaadimavyayam.
13. But the great souls, O Arjuna, partaking of My divine nature, worship Me with a single mind (with the mind devoted to nothing else), knowing Me as the imperishable source of beings!

Satatam keertayanto maam yatantashcha dridhavrataah;
Namasyantashcha maam bhaktyaa nityayuktaa upaasate.
14. Always glorifying Me, striving, firm in vows, prostrating before Me, they worship Me with devotion, ever steadfast.

Jnaanayajnena chaapyanye yajanto maamupaasate;
Ekatwena prithaktwena bahudhaa vishwatomukham.
15. Others also, sacrificing with the wisdom-sacrifice, worship Me, the all-faced, as one, as distinct, and as manifold.
