The lotus is the sacred flower in Hinduism, Buddhism and Jainism.It is symbolic of purity of thought , word , deed and body.Just like the lotus blooms fresh and pure above muddy waters ( symbolizes worldly attachments ) , so should we strive towards truth and purity
“He who carries out his activities without attachment, attributing the agency of his activities to Prakriti ( Nature ) is untouched by them as a lotus leaf is unaffected by water ”
Srimad Bhagavad Gita
