What you do, what you eat, what you offer, what you donate,
What austerity you perform, O son of Kunti, do that as an offering to Me.

O Arjuna, whatever you do, whatever you eat, whatever you offer as oblation to the sacred fire, whatever charity you give, whatever austerity you perform, do all that as an offering unto Me. (See also 12.10, 18.46)
O son of Kunti, all that you do, all that you eat, all that you offer and give away, as well as all austerities that you may perform, should be done as an offering unto Me.
