From an energetic standpoint, insecurity has to do with third chakra and more speciﬁcally the stomach organ. The stomach (not to be confused with the abdomen) is an organ about the size of your ﬁst and sits to the left of your sternum. This organ, on an emotional level has to do with how you see yourself in the world. It is no wonder why obesity is such a problem because overeating is the easiest way to numb the stomach from emotions and it allows us to avoid feelings about ourselves.
Here is a great kriya for working with the stomach and to work with issues around insecurity. It is important to not only practice the kriya, but allow yourself to consciously be aware of anything that you are feeling to discover the roots of your insecurity.
