 Responses to evolutionary theory were as diverse as Christian views on this subject, ranging from creationism (denial of evolutionary theory based on a perceived incompatibility with Vedic texts) to acceptance (see C.M. Brown 2012 for a thorough overview). Authors such as Dayananda Saraswati (1930–2015) rejected evolutionary theory. By contrast, Vivekananda (1863–1902), a proponent of the monistic Advaita Vedānta enthusiastically endorsed evolutionary theory and argued that it is already prefigured in ancient Vedic texts. His integrative view claimed that Hinduism and science are in harmony: Hinduism is scientific in spirit, as is evident from its long history of scientific discovery (Vivekananda 1904). Sri Aurobindo Ghose, a yogi and Indian nationalist who was educated in the West, formulated a synthesis of evolutionary thought and Hinduism. He interpreted the classic avatara doctrine, according to which God incarnates into the world repeatedly throughout time, in evolutionary terms. God thus appears first as an animal, later as a dwarf, then as a violent man (Rama), and then as Buddha, and as Kṛṣṇa. He proposed a metaphysical picture where both spiritual evolution (reincarnation and avatars) and physical evolution are ultimately a manifestation of God (Brahman). This view of reality as consisting of matter (prakṛti) and consciousness (puruṣa) goes back to sāṃkhya, one of the orthodox Hindu darśana, but Aurobindo made explicit reference to the divine, calling the process during which the supreme Consciousness dwells in matter involution (Aurobindo, 1914–18 [2005], see C.M. Brown 2007 for discussion).
