There are entities in the Universe, with which man has to deal; they are:Paramatma, Prakriti andJivatma, God, Nature and Man. Of these, Go has to be worshipped by man, to be realised by man through Nature or Prakriti.

Nature is the name for all the various items that impress upon man the glory and the splendour of God. It is called Maya too. Maya is the vesture of God, which hides as well as reveals His Beauty and Majesty. Man must learn to use Nature not for his comfort or entanglement to the utter forgetfulness of the God behind the joy he derives, but for the better understanding of the Intelligence that guides the Universe. (S.S.S Vol. V - p. 326)

All karma done for the sake of three entities is sacrifice, viz., to utilise the world for the worship of the Lord, to establish peace and justice in society and to control and co-ordinate the functions of the body. The first is called Yajna, the second Dana and the third Tapas. All human acts must subserve these three needs. (Prema Vahini, p. 11)
