Question - Gurudev, what is Kundalini Shakti? What happens when it rises during Hollow and Empty meditations?

Gurudev Sri Sri - Kunda means pot, kundalini means energy in the pot. The body is like a pot. When the energy in the body rises up, it has many manifestations. All different emotions are just manifestations of one beautiful energy. It is one energy that manifests in different regions of the body. At the bottom of the spine, it is inertia or enthusiasm. When it moves up, it is creative or procreative energy (sex drive). When it moves up, then the energy manifests as joy, generosity or greed or jealousy. As it goes up to the heart region, it manifest as love, fear or hatred. Then in the throat, the energy manifests as grief or gratefulness, and so on.
