Lotus flowers only grow in really swampy areas, so they symbolise the idea that out of ugliness and destruction, we can all miraculously bloom in a beautiful flower. This is why they are symbols of rebirth and resilience.
According to Feng shui expert Adjie Cho (from holistic spaces), the lotus can also be thought of as an embodiment of a mandala, with a center point that expands outward. Pink is a soft color that invites feminine energies.
