The second chakra is the sacral chakra. It is also called Svadisthana. This chakra is located in the lower abdomen and genitals. The element associated with this chakra is water and the color associated with it is orange. This chakra brings pleasure, desire, creation and procreation to ones life.
When this chakra is in balance, one can experience a normal sex drive, a strong lower back, good circulation, and hormonal balance, creativity, sensuality, enthusiasm, devotion and charisma. When it is out of balance, one might experience kidney and bladder conditions, reproductive disorders, an abnormal sex drive, obsession with oneself or money, or a creative block.
If this chakra is out of balance, there are many ways to work on getting it back in balance. One can use a specific pranayama technique called Nadi Shodhana, which is alternate nostril breathing. There is focusing on the mandala at the right (link). One might chant the word Vam and meditate. One could try more physical activities such as swimming, giving or receiving a massage, taking a bath, or even doing something more creative.
Finally, the poses that one might do in yoga that would help balance this chakra include twists and pelvic rotations, cat/cows, frog, reclining bound angle, and omega pose.
Namaste my friends,
