The Ashtamangala is not one fixed list but two, and John Powers's account of Tibetan Buddhism is explicit that the widely reproduced set, parasol, golden fish pair, treasure vase, lotus, conch shell, endless knot, victory banner and dharma wheel, belongs specifically to the Tibetan Buddhist tradition rather than to Buddhism as a single unbroken inventory.
The Jain eight auspicious symbols are drawn from an older and separate list tied to a set of auspicious dream omens recorded in Jain scripture, sharing the number eight and the general idea of auspiciousness with the Buddhist set but not its specific membership, and the two traditions developed their respective eight-symbol groupings independently rather than one borrowing directly from the other. Treating Ashtamangala as though it names a single fixed inventory across all Buddhist and Jain contexts is the most common error in popular treatments of the set, and this atlas records the two lists as genuinely distinct groupings that happen to share a name and a count. Individual items within the Tibetan set are also independently significant Buddhist symbols in their own right outside the group, the dharma wheel above all, which functions across the whole of Buddhism, not only in Tibetan practice, as the single most recognized emblem of the Buddha's teaching.
