11.25.23

mad-arpaṇaṃ niṣphalaṃ vā sāttvikaṃ nija-karma tat /
rājasaṃ phala-saṅkalpaṃ hiṃsā-prāyādi tāmasam //

23. Any prescribed action of permanent nature performed to be offered to Me, and without any desire for fruit is Satvika; that

which proceeds with the hope and wish for fruit is Rajasa and that which becomes mostly harmful or is hypocritical and so on, is Tamasa.
