“Muladhara (Sanskrit: मूलाधार, IAST: Mūlādhāra, English: “root support”) or root chakra is symbolized by a lotus with four petals and the color red. This center is located at the base of the spine in the coccygeal region. It is said to relate to the gonads and the adrenal medulla, responsible for the fight-or-flight response when survival is under threat.
Muladhara is related to instinct, security, survival and also to basic human potentiality. Physically, Muladhara governs sexuality, mentally it governs stability, emotionally it governs sensuality, and spiritually it governs a sense of security. Muladhara has a relation to the sense of smell.
This chakra is where the three main nadis separate and begin their upward movement. Dormant Kundalini rests here, wrapped three and a half times around the black Svayambhu linga, the lowest of three obstructions to her full rising (also known as knots or granthis). It is the seat of the red bindu, the female drop (which in Tibetan vajrayana is located at the navel chakra).[clarification needed]
The seed syllable is Lam (pronounced lum), the deity is Ganesh, and the Shakti is Dakini. The associated animal is the elephant.
The corresponding deity for material element of this chakra is Prithvi.” ~Wikipedia
