"Readers of the Bhagavad Gita will also remember the teaching of love and devotion with which it is filled... He varies the type of religion to suit the period of the world’s history at which it is put forth, and the people to whom it is given; but though the form may vary as evolution proceeds, the ethics are ever the same."
