This episode compares three distinct Buddhist mandalas, revealing their shared Mahāyāna roots and unique doctrinal emphasis. Nichiren’s Calligraphic Mandala, or Honzon, uses kanji characters for devotional chanting, symbolizing the practitioner's inherent Buddhahood and focusing on the Lotus Sutra. In contrast, Kūkai’s Womb World Mandala is a pictorial aid for esoteric visualization in Shingon Buddhism, depicting the compassionate aspects of the cosmic Buddha Mahāvairocana. Finally, the Kālacakra Mandala, prominent in Tibetan Vajrayāna, is an elaborate painting or 3D sand creation used for advanced tantric practice, focusing on the intricate relationship between time and cycles to guide practitioners toward enlightenment.
