The tall trees are 'too proud' to bend and surrender to the winds, whereas the humble blade of grass will bend and surrender to the mighty wind. When the rain pours over the mountains, when the mighty winds blow, the tall trees on the mountains may fall down, but the gentle blade of grass will bend and survive. The metaphor of gentle blade of grass at the foot of the mountain is very profound. The song says, be humble like a blade of grass at the foot of the mountain and spread your fragrance like a gentle jasmine flower. It advises us to be humble and gentle yet strong.
This short and beautiful poem holds the key for leading a balanced life.
