no return

As with Heraclitus’ famous remark, ‘You cannot enter the same poem twice’.

shaping music

As do the poets, Heraclitus follows language where it leads him, where he is receptive to its inward and autonomous authority, with somnambular yet acutely lucid trust. Hence his recurrent attempts to characterize, to make us party to the twilight zone between sleeping and waking. Day melts into night, night begetting day in subversion of the trenchant Mediterranean light. There is here no distinction between philosophic or scientific finding and poetic form. The springs of thought are identical in both (poiesis). Poetry betrays its daimon when it is too lazy or self-complacent to think deeply (Valéry’s astreindre). In turn, intellection falsifies the shaping music within itself when it forgets that it is poetry.

after heraklitas

One can’t wade into the same line of poetry twice.

unapparent harmony

Heraklitas states "an unapparent harmony is more powerful than an obvious one." And so it is with all superior metaphors in poetry.
