The 3 colours of the oni symbolize the 'sandoku' (三毒 the '3 kleshas'). In Buddhism kleshas are mental states that cloud the mind, poison the heart, and manifest in unwholesome actions.
❤️greed/desire (貪欲)
💚ill-will/anger (瞋恚)
🖤ignorance/folly (愚痴)
More than just sybolizing greed, anger and ignorance, the oni also embody ill fortune and impurity.
Before the dance the red 'leader' oni blesses worshippers, taking on their 'klesha'.
When the demons are finally chased away and cast out, they take everyone's bad luck with them.
A sweet delivery for Setsubun...Oimatsu's "ofuku" (於福).
Ofuku is a cheerful, plump-cheeked woman that has become a symbol of Setsubun. The character '福' (fuku) in her name means 'luck'.
I wonder what the collective noun for a group of Ofuku is🤔 ......a 'blessing' of Ofuku?
