the ultimate purposes for the existence of living things. To obtain and broaden the knowledge of the world for spiritual perfection, many refer to the Bhāgavata for guidance because it draws upon a scientific and theological dialogue. Hinduism offers methods to correct and transform itself in course of time. For instance, Hindu views on the development of life include a range of viewpoints in regards to evolution, creationism, and the origin of life within the traditions of Hinduism. For instance, it has been suggested that Wallace-Darwininan evolutionary thought was a part of Hindu thought centuries before modern times. The Shankara and the Sāmkhya did not have a problem with the theory of evolution, but instead, argued about the existence of God and what happened after death. These two distinct groups argued among each other's philosophies because of their texts, not the idea of evolution. With the publication of Darwin's On the Origin of Species, many Hindus were eager to connect their scriptures to Darwinism, finding similarities between Brahma's creation, Vishnu's incarnations, and evolution theories. Samkhya, the oldest school of Hindu philosophy prescribes a particular method to analyze knowledge. According to Samkhya, all knowledge is possible through three means of valid knowledge – Pratyakṣa or Dṛṣṭam – direct sense perception, Anumāna – logical inference and Śabda or Āptavacana – verbal testimony. Nyaya, the Hindu school of logic, accepts all these 3 means and in addition accepts one more – Upamāna (comparison). The accounts of the emergence of life within the universe vary in description, but classically the deity called Brahma, from a Trimurti of three deities also including Vishnu and Shiva, is described as performing the act of 'creation', or more specifically of 'propagating life within the universe' with the other two deities being responsible for 'preservation' and 'destruction' (of the universe) respectively. In this respect some Hindu schools do not treat the scriptural creation myth literally and often the creation stories themselves do not go into specific detail, thus leaving open the possibility of incorporating at least some theories in support of evolution. Some Hindus find support for, or foreshadowing of evolutionary ideas in scriptures, namely the Vedas. The incarnations of Vishnu (Dashavatara) is almost identical to the scientific explanation of the sequence of biological evolution of man and animals. The sequence of avatars starts from an aquatic organism (Matsya), to an amphibian (Kurma), to a land-animal (Varaha), to a
