Group together as religions those systems of thought and their institutions that make specific truth claims about<p>1. Origins of the cosmos and, specifically, homo sapiens
2. Existence (or not) and nature of super-human sentient beings, their character and agency
3. What happens after death
4. Some root cause of all problems faced by individuals, tribes, nations, and humanity
5. Prescribed and proscribed behaviors that eliminate the root cause of problems<p>This description covers, to my knowledge, Judaism, Christianity, Islam, Buddhism, and Hinduism, all in their many varieties.<p>Inasmuch as I have my own answers to these questions, then by my own definition I'm religious, though I am not backed by a state-spnsored institution :)<p>My path is best described as Buddhist, without reincarnation or supernatural "devas" that were syncretically added even as Sidhhata Gotoma's dead body was still warm.
