He described the universe as a manifestation of consciousness coming under the bondage of its own nature, resulting in creation. His spiritual and social philosophies embraced diversity as the law of nature; a result of Singular Consciousness expressing itself in numerous forms. Sarkar advocated for the welfare of humans and the planet through his socio-economic philosophy of Prout, which is rooted in the idea of Neohumanism, a worldview based on inter-connectedness of all beings.
