Not a deity but a central aesthetic and philosophical concept: the poignant awareness of the impermanence of things and the gentle sadness at their passing, often associated with cherry blossoms.

The river of forgetfulness in the Underworld, whose waters cause souls to forget their past lives, symbolizing the ultimate dissolution of individual identity and experience.

The essence of that which is powerful but intangible, here and then gone, like a gust of wind that cannot be grasped or held.

The quality of being temporary and ever-changing, like the wind which can be felt but never held, reminding us of the transient essence of all phenomena.

The quality of being present only for a fleeting, liminal moment, emphasizing the preciousness and transient opportunity of creative inspiration.

The essential quality of impermanence in all phenomena, the understanding that every form is a temporary arrangement.
