with grass here for my pillow

Where are they going, the fireflies that rise at night? And I, with grass for a pillow, do not know where I am bound.
Commentary
Book Three Summer Poems 272

Headnote: composed on seeing fireflies rise into the air.
A run on fireflies begins here. They appeared already in the two hundred and fifty-fifth poem; here they are set in a night spent travelling. The headnote records that the poem was written on seeing them rise.
Mibu no Tadami, a son of Mibu no Tadamine, was a mid-Heian poet and one of the thirty-six immortals of poetry. In Book One he is the poet of the twelfth and seventy-eighth poems. Tadamine, poet of the two hundred and eighty-third, was his father.
The time is a summer night; the place is a field on a journey.
The occasion was the sight of the fireflies.

The word in the first line means to where; an interrogative particle follows and governs the auxiliary in the third line.
The second line names the insects.
The auxiliary in the third line expresses present conjecture. Fireflies rising high are taken to be climbing toward some destination.
The fourth line means not knowing where one is going. It can be read of the fireflies and of the poet at once, and in one phrase the traveller's own condition is laid over theirs.
The poem closes on a noun meaning a night's rest on a journey. A traveller lying on the ground and insects rising into the air are set against each other, and two conditions are given by direction, down and up.
