このみちをたどるほかない草のふかくもno way but to follow this road though the grass grows deep

草が深く茂って道を覆っても、この道をたどるしかない。目の前の一本道のことであり、自分の生き方のことでもある。ためらいの「も」を残しながら、それでも足は前へ出てゆく。Even where the grass grows thick and hides the way, there is no choice but to follow this road. It is the single path before him, and it is also his way of living. The lingering "though" holds a moment of hesitation, yet the feet still step forward.
