What is the meaning of this poem?

im not exactly sure since i didn't write it and only the writer would know precisely what they were trying to get across but i interpreted it being about life. i think the river is life, we and we are the petals. we float through life like the petals in the river "frighted with hope...joy" and we come across things but then life eventually sweeps us away from them them but we still we made some impact. we stay with them somehow like the scent of the flower.
