There is a big tree for one flower to bloom.
ひとつの花が咲くために、大きな木がある。

In order for a big tree to grow to its fullest potential, moss and ivy grow with all their might.
大きな木がその力の限り大きくなるために、苔も蔦も一心に育つ。

It's fine as is.
そのままでよい。

Each of us will continue to do what is best for the situation.
それぞれのまま、状況に応じた一番のことへ向かってゆく。

Live your life with a relaxed mind and depending on the situation.
心をゆるゆると、その状況にまかせて生きてゆく。

The light shines brightly, and it continues to live as it is in its beauty.
光がキラキラ輝く、その姿の美しさのまま生きてゆく。
