Bhagavad Gita Chapter 17 Verse 11

Gita 17.11

अफलाकाङ्क्षिभिः, यज्ञः, विधिदृष्टः, यः, इज्यते,
यष्टव्यम्, एव, इति, मनः, समाधाय, सः, सात्त्विकः।।11।।

Gita 17.11

AflaakaankshibhiH, yagyaH, vidhidrshtH, yaH, ijyate,
Yashtvyam’, ev, iti, manH, smaadhaay, saH, saattvikH ||11||

Translation: (YaH) which (vidhidrshtH) directed by the injunctions of the scriptures (yagyaH) yagya (yashtvyam’, ev) to perform only is a duty (iti) thus (manH) mind (smaadhaay) by resolving (aflaakaankshibhiH) those who do not desire for the result (ijyate) is performed (saH) that (saattvikH) is Satvik. (11)

Translation: It is a duty to only perform yagya directed by the injunctions of the scriptures – with such resolution of mind a yagya, which is performed by those who do not desire for the results, is Satvik.

Important: - Although in above-mentioned Verse 11, the distinctive description of Satvik yagya is said to be according to the scriptures, but without finding the Tatvdarshi Saint mentioned in Gita Gita Chapter 4 Verse 34, this Satvik sadhna[1] is also futile because in Gita Chapter 17 Verse 1, Arjun has asked about those who abandoning the injunctions of the scriptures act arbitrarily, which has been described as futile in Gita Gita Chapter 16 Verse 23-24. Therefore, here only those who act arbitrarily out of their nature are being described. This sadhna is also useless.
