Forms of religion

Main Types

Monotheism: Worship of one god alone. It is different from Pantheism and Pantheistic
- e.g. Abrahamic religions
Polytheism: Worship of many gods.
- e.g. Egyptian Gods, Greek Gods
Henotheism: Worship of one supreme god doesn't mean you can't have other gods.
- e.g. Hinduism
Animism: All entities possess a spiritual essence.
- e.g. Hinduism, Buddhism, Jainism, Sikhism
Pantheism: Reality itself is what we call god. It is distinct from Panentheism in that god is not distinct from the world.
- e.g. Hinduism, Taoism, Sikhism, Confucianism
Pantheistic Animism - The belief that all reality has a single soul and that is god.
- e.g. Giordano Bruno's religion.
Panentheism: God intersects every part of the universe and also extends beyond space and time. It is different from Pantheism in that god is a distinct quality from the world.
- e.g. Hinduism (Advaita Vedanta, Achintya-Bheda-Abheda)
Monistic Theism: A combination of Pantheism and Panentheism, but does not attribute personality to god. This is the core idea of Hinduism
Substance monotheism: The belief that there are many different gods, but that they are all essentially forms of the same essence

Agnostic Theism (Whether god exists or not cannot be known)
Ietsism (Agnostic Atheism, Spiritual but Not Religious) (Tends to be more skeptical about the idea of god itself)

Pan-theism (All is God) (Hinduism)
Pan-en-theism (All is in God) (Hinduism (Brahmaan-Creation) (Achintya Bheda-Abheda, Dvaitadvaita (differential monism), Vishistadvaita (qualified monism)), Kashmir Shaivism, Shakti/Tantra, Kabbalah/Jewish Mysticism)
Pan-deism (God became All)
Monism (There is only one thing at the deepest level) (Vedanta)
Dualism (Dvaita Vedanta, Taoism (Yin-Yang))
Ignosticism/Igtheism (God is a incomprehensible entity, hence religions are meaningless (e.g. "God created everything except Himself" is meaningless))
Omnism (Belief in all religions as possible)
Transtheism (God is not an important aspect of reality)
