Swadhisthana, is symbolized by a white lotus within which  is a crescent moon, with six orange petals (According to Wikipedia).

This is the second chakra and known as the Sacral Chakra  (Svadhisthana) and is located in the abdomen and lower  back. It’s related to emotions, connecting us to others  through love at a deeper spiritual level with possible soul connections (Debbie Creagh).

This chakra relates to the physical functions of the Small and Large Intestines, Appendix,  Testicles, Ovaries, and inter-relationships with mammary glands in the breasts.

Congested energy in this chakra can lead to Sexual problems, back problems, problems with  reproductive organs, spleen, and urinary system (Lee Wei-Dei).
