Each bow expresses one of the four Buddhist vows. These vows are: “Although sentient beings are innumerable, we vow to save them. Although our evil desires are limitless, we vow to be rid of them. Although the teaching is limitless, we vow to learn it all. Although Buddhism is unattainable, we vow to attain it.” If it is unattainable, how can we attain it? But we should! That is Buddhism.
