त्रैगुण्यविषया वेदा निस्त्रैगुण्यो भवार्जुन ।
निर्द्वन्द्वो नित्यसत्त्वस्थो निर्योगक्षेम आत्मवान् ।।
traiguṇyaviṣayā vedā nistraiguṇyo bhavārjuna ।
nirdvandvo nityasattvastho niryogakṣema ātmavān ।।
तावान्सर्वेषु वेदेषु ब्राह्मणस्य विजानतः ।।
yāvānartha udapāne sarvataḥ saṃplutodake ।
tāvānsarveṣu vedeṣu brāhmaṇasya vijānataḥ ।।

Vedas proclaim benefit for people who are normally filled with Triguna-s. Usually one of these guna-s is in excess in each of us. People with rajas-tamas guna expect samsara-phalas from the sacrifices specified in vedas. They are not intent on obtaining moksha
A small comparison of mother & child here will help. A child asks for his favorite food. Mother refuses. One child may adjust while another may not..
The same is the case with vedas. It prescribes a variety of sacrifices for obtaining variety of phala-s. Each man to his needs!
He instructs Arjuna to obtain ever increasing sattva guna & always aim to seek/realize Atma
Similarly, the vedas are an ocean. A mumukshu (person seeking moksha) should only seek a small part of it which help him in realization of Atma

Vedas have triguna-s as their subject matter. Arjuna, you be devoid of triguna-s & dvandva-s (twin pairs as told above). Always be filled with sattva without any attachment to yogakshema (worldly benefits)

Arjuna, the outcome of vedas are filled with triguna (svarga etc..) They are temporary. You should not seek it but instead be fixated upon moksha & realizing Bhagavat Svarupa. Always mediate on Paramatma acknowledging that He is different from you & He's your Master
