Lotus flowers play a vital role in Buddhism. They generally represent spiritual awakening, purity, and faithfulness. This belief roots from the fact that lotus flowers emerge from muddy waters. For Buddhism, that means the act of rising above despite the challenges and moving towards the light of wisdom. Buddhists consider the petals to depict the opening of the heart.
In Buddhism, the journey of the lotus is said to mirror our own spiritual journeys. Mired in suffering (or samsara), our spirits start out like a lotus bud, tightly closed and buried in deep in the muddy dark. It is only by living through Buddhist virtues and working our way through varied experiences that we can slowly open ourselves to enlightenment. Buddhists also regard the lotus as an important symbol of non-attachment: it remains firmly planted in the mud while growing high above the water’s surface, unsullied by the dirt that surrounds it.   
As a lotus flower is born in water, grows in water and rises out of water to stand above it unsoiled, so I, born in the world, raised in the world and having overcome the world, live unsoiled by the world.Buddha referred to the lotus in his teachings as a powerful metaphor
The lotus appears frequently in Buddhist mythology, art, and scripture. Art and statues of Buddha often depict him seated on top of a lotus. Legend has it that when he was born, lotuses in grew in Buddha’s footsteps. The most important text in Mahayana Buddhism is referred to as the Lotus Sutra and contains the final teachings of Buddha. The Tibetan Mantra, Om Mani Padme Hum, one of the most widely used mantras within Buddhism, also alludes to the lotus flower and is said to invoke the bodhisattva of compassion.
The lotus is unusually rooted in the mud, deep beneath the water’s surface, where it eventually breaks through to the air and sunlight, then blossoms into a beautiful flower, symbolizing purity, enlightenment, and resurrection. The flower has long been a metaphor for the human being mired in the egoic sense of self before waking up to its self-created darkness and being born in the light. For this reason, the lotus plays a central role in Indian religious art of the Hindus, Buddhists, Sikhs, and Jains. Lotus thrones commonly adorn the pedestals of most important figures in Buddhist art. During the Pala period (1000 B.C.E.), the Blue Lotus adorned a statue of Tara, a leading advocate of Buddhist philosophy in eastern India.   
There is the mud, and there is the lotus that grows out of the mud. We need the mud in order to make the lotus. Renowned Buddhist monk Thich Nhat Hanh
It is difficult to say whether the Blue Lotus is more revered for its symbolism of the universe, or for its healing properties and powers. Or perhaps the two are inseparable. The Hindus consider the lotus seed to be especially sacred because it contains a complete template for the adult plant as the divine form in the process of manifesting into physical expression. The eight- petaled lotus common to Buddhist mandalas speaks to cosmic harmony.   
In Buddhism, the symbolism of a lotus flower also differs depending on its colour. For instance, a blue lotus flower symbolizes a spirit’s victory over knowledge and wisdom. White lotuses signify peace and purity, while red lotuses, much like other red flowers, mean love and compassion. Purple lotus flowers, on the contrary, have a deeper meaning as their petals represent important teaching of Buddha called the Noble Eightfold Path. The pink lotus flower, however, gives an essential sense in Buddhism. It is regarded as the “true lotus” and the primary colour of the flower.
