Lotus

Lotus seed (lotus heart): only through bitterness can we find sweetness.

Lotus flower, a symbol of purity and resilience in Vietnam, embodies beauty rising from adversity.

"Nothing in the pond is more beautiful than the lotus
Green leaves, white flowers with yellow pistils
Yellow pistils, white flowers, green leaves
Near the mud without the foul smell of mud."

Lotus flower grows out of swamp but not associate with the swamp.

It is free from swamp and clean. This symbol is taken to represent an arahant (one who is free from three poisons: greed (craving), anger (hatred), and delusion (ignorance). The swamp is the unwholesome mentality.
