अफलाङ्क्षिभिर्यज्ञो विधिदृष्टो य इज्यते | यष्टव्यमेवेति मनः समाधाय स सात्त्विकः
aphalāṅkṣibhiryajño vidhidṛṣṭo ya ijyate . yaṣṭavyameveti manaḥ samādhāya sa sāttvikaḥ
那種依照經典規範，由不希求結果之人所行，並懷著「這確實是義務」的信念而完成的祭祀，是屬於悅性（薩特瓦，Sattva）的。
That sacrifice which is in accordance with the injunctions, (and is) performed by persons who do not hanker after results, and with the mental conviction that it is surely obligatory, is done through sattva.
當祭祀以所有應有的悅性儀式、信念和虔誠來進行，絲毫不帶有對回報的渴望，心靈專注於祭祀本身，僅為履行職責而行時，便被稱為本質純淨。此處的祭祀是以無私或無欲（Nishkamya Bhava）的精神進行，作為獲得「阿特曼」（Atman，自性）知識的輔助。這種無私無欲的行為能淨化心靈，為修行者接受神聖之光或自性知識做好準備。一個悅性之人會被其本性驅使去進行此類無私無欲的祭祀，他甚至不關心自己的解脫，只是堅信這些是必須履行的職責。此處的「 यज्ञ 」（Yajna，祭祀）不限於儀式性祭祀，而是廣義指任何無執著、無我執、無回報期望，作為獻給上主的無私行為。
When a sacrifice is done with all due Sattvic rites? faith and devotion? without the least taint of desire for reward? with the mind fixed on the sacrifice only? for its own sake (for the,sake of discharging the duty only)? then it is said to be pure in its nature. Here the sacrifice is done in a disinterested spirit or with an attitude of desirelessness (Nishkamya Bhava) as an auxiliary to the attainment of the knowledge of the Self. Such selfless and desireless actions purify the mind and prepare the aspirant for the reception of divine light or knowledge of the Self. The Sattvic nature of a man forces him to do such selfless and desireless sacrifices. He does not care even for his own emancipation. He performs them with the firm belief that they ought to be done. He does them with the firm resolve that sacrifice is a duty.Yajna here is not limited to the ceremonial sacrifice. It is used in a broad sense. Any unselfish action done without attachment? without agency or egoism and without expectation of reward? as an offering unto the Lord? is a Yajna or sacrifice.
