Bhagavad Gita 9.27

यत्करोषि यदश्नासि यज्जुहोषि ददासि यत् ।
यत्तपस्यसि कौन्तेय तत्कुरुष्व मदर्पणम्  ॥

yat-karoṣi yad-aśnāsi yaj-juhoṣi dadāsi yat
yat-tapasyasi kaunteya tat-kuruṣva mad-arpaṇam – 27 

O Kaunteya, whatever you do, whatever you eat, whatever oblation you offer to fire, whatever you give as dāna or gift, whatever austerity you perform, make it all a wholesome offering to Me (the Supreme).
