You will learn how to feel your own energy body and hold your own energetic space, which will eventually help you to ground your energy. With time, you will begin to understand the difference between your energy influences and others, so you can know what is your stuff (energetically) and what is someone else's influence over you.
You need a strong working energy system to navigate other non-ordinary-reality realms and you need some knowledge to do it safely.
If you are a Healer, Practitioner, Energy Worker or hold large groups of people in events and workshops, then you will also benefit from learning energy techniques to ensure that you can hold powerful clean energetic spaces in your own clinics and client interactions.
By strengthening the lower energy centres we improve our physical condition and vitality, which gives us a strong enough base to support opening our heart and third eye centres.
