Grounding to Mother Earth - being properly grounded to the Earth is crucial for our survival as individuals and as communities during incarnations on this planet. By remaining connected to the centre of the Earth, we are also able to connect to the rest of the solar system, the galaxy and the universe, becasue our planet is our connection to the rest of the cosmos.  When we are not grounded (and it is possible for large groups of people and entire nations to become "ungrounded"¸ particularly when it has been in a crisis situation for many years), we can become easily stressed¸ tired and irritable, like a tree whose roots do not reach deeply enough into the Earth, easily blown over in a passing wind. When we are grounded, we are able to receive pure earth energy, which we need on a daily basis, directly from Mother Earth, who is a living, breathing consciousness with whom we can communicate at a very deep level. 

Perception - the way one perceives the world and oneself, via the 5 senses, as well as the "6th sense". 

Subtle bodies (see pic on the right): 

•  Etheric - the subtle body closest to the physical, which contains the blueprint for what is currently manifesting at a physical level.
• Emotional - the subtle body where we store most of the unresolved feelings from the past which we were not able to fully experience at the time, and which were suppressed. 
•  Mental - where we store our beliefs and notions about ourselves and the world, many of which are taught to us by our culture and community, and some of which may no longer serve a purpose for us as beings.
• Spiritual - where we store energies related to our spiritual lives and development, and our connection with Source.
• Etheric Template (also known as causal body #1), one of the outer layers of the auric field, holding the "ideal blueprint" for the physical body and auric field.
•  Celestial Body (also known as the causal body #2), said to be the subtle body through which we are able to experience spiritual bliss.
•  Ketheric template (also known as the causal body #3) - the outermost and most subtle layer of the auric field, holding "imprintings" from past lives and unresolved childhood memories, as well as carrying "imprintings from the current  life into the next life.
