The Jikkai Great Mandala refers to the Ten Realms (Jikkai), a foundational concept in Japanese Buddhist thought, particularly within Nichiren Buddhism, representing the ten states of existence ranging from hell to Buddhahood. Depicted or inscribed in mandala form, it is traditionally used as an object of veneration and contemplation, illustrating the interconnectedness of all states of being within the Buddhist cosmological framework. While its symbolism has been described as encompassing all phenomena, including the natural world, claims about specific effects or benefits attributed to it should be approached with care and are best explored through the teachings of the traditions that hold it sacred.
