The Navel Chakra (Manipurara) is located exactly on the hara point. It connects us to the energy field of every other being on earth and is responsible for a global sense of unity. The Navel Chakra ensures that you find the incarnated members of your soul family. It also helps you to recognize them.
Its color is bright orange.
Ask yourself:
Am I already walking my highest soul path and am I connected to my soul family?
Nothing with frequencies could be found here. But you can use the above mantra for the meditation. I know from a reliable source that this mantra is also used for activating the Navel Chakra, although this is not mentioned in the video description.
