" Although there are tremendous differences in the particular expressions of any one branch within each religion, core teachings tend to remain central to all branches of a given religion—each branch generally shares the same core texts, teachings, saints, and/or founders. For example, love is a core value among the many Christian traditions, ahimsa is central to each Hindu tradition, zakat is obligatory in all Muslim traditions, and the list goes on. "
