mad-arpaṇaṁ niṣphalaṁ vā
sāttvikaṁ nija-karma tat
rājasaṁ phala-saṅkalpaṁ
hiṁsā-prāyādi tāmasam
mat-arpaṇam - offered unto Me; niṣphalam - done without expectation of result; vā - and; sāttvikam - in the mode of goodness; nija - accepted as one's prescribed duty; karma - work; tat - that; rājasam - in the mode of passion; phala-saṅkalpam - done in expectation of some result; hiṁsā-prāya-ādi - done with violence, envy and so on; tāmasam - in the mode of ignorance.
Ordinary work performed as an offering to God, without desire for the result, is understood to be in the mode of goodness, whereas activities of devotion — such as chanting and hearing the glories of the Lord — are transcendental forms of work beyond the modes of nature.
