A socio-cultural system encompassing various behaviors, practices, texts, prophecies, religious organizations, and spiritual aspects constitutes a religion. The study of world religions is a broad category within the realm of religious studies, focusing on the largest and most widespread religious traditions. The "Big Five" religions typically include Christianity, Islam, Hinduism, Judaism, and Buddhism, with Sikhism, the Bahá'í Faith, and Zoroastrianism also being considered significant. These major religions are often contrasted with new religious movements and indigenous traditions. The world religions paradigm was developed to expand the scope of religious inquiry. This book attempts to understand the critical aspects that fall under the discipline of world religions and how such aspects affect socio-cultural dimensions of humankind. It is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of world religions. This textbook will serve as a reference to a broad spectrum of readers.
