The life of Salmon is predictable but Silver Salmon is different. He wants to challenge himself into taking a different route rather than following the line that he's supposed to follow.
Silver Salmon takes you to a journey where he wants to find answers for his questions. It usually involves the meaning of life and death, growing up, love, nature and the relationship between nature and humans.
"There are countless humans who do cruel things simply in order to show that they can,' he said. 'Why is the earth a den of thieves? Why are murders committed there every day? Humans are more cruel than we salmon can imagine. How could we ever trust those who invented war?"
"There's an old saying: if at first you don't succeed, try, try again. So even if we fail the first time, we have to take up the challenge a second time, a third time, even a fourth time"
"The teacher seems to think that lessons are the be-all and end-all of life. Perhaps, even while watching the fallen leaves floating on the river's surface, he's thinking about morals that could be drawn from it. If he were to come across a flower he hadn't seen before, rather than marvelling at its beauty, he would bury his head in an illustrated guide to plants, wanting to know only whether there was some partical benefit to be had from flower... He doesn't understand that flowers and stars are beautiful in themselves."
