mad-arpaṇaḿ niṣphalaḿ vā

hiḿsā-prāyādi tāmasam
mat-arpanam -- offered unto Me; nishphalam -- done without expectation of result; va -- and; sattvikam -- in the mode of goodness; nija -- accepted as one's prescribed duty; karma -- work; tat -- that; rajasam -- in the mode of passion; phala-sankalpam -- done in expectation of some result; himsa-praya-adi -- done with violence, envy and so on; tamasam -- 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.
