SB 11.25.23
mad-arpanam nisphalam va
sattvikam nija-karma tat
rajasam phala-sankalpam
himsa-prayadi tamasam
Translation:
Work performed as an offering to Me, without consideration of the fruit, is considered to be in the mode of goodness. Work performed with a desire to enjoy the results is in the mode of passion. And work impelled by violence and envy is in the mode of ignorance.
Purport:
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.
