You might think of the immune system as a part of the physical body only. However, this is not the case. It is just as important to develop a strong psycho-emotional and spiritual immune system through a strong focused mind that clears Negative Ego. Also the effectiveness of your physical immune system will, in actuality, depend to a great extent on the strength of your psychological and spiritual immunity and one’s willingness to clear the Negative Ego and the Pain Body.
Whether spiritual people like to admit it or not, Life in this dimension is a battle that one must develop strength and discipline. Even the great Paramahansa Yogananda said, “Life is a Battlefield”. This discipline exists on a variety of levels and one must learn to be a spiritual warrior in life. First you are disciplining your mind to remain conscious and stay awake in a reality where the mass populace is generally asleep to their environment and their divine nature. Staying out of automatic pilot and from letting the subconscious mind control your life takes constant vigilance to stay mentally alert and stay present in the moment. Second, keeping negativity and negative thoughts away from your energy field and thought processes takes disciplined awareness. As well does the ability to maintain staying in the flow and remain balanced and in harmony with yourself in order to have clarity and inner peace.
With the plethora of new energies and resultant dimensional shifting, there is also a battle to maintain personal health and heal from physical imbalances through healing the experiences of unresolved life trauma, conflicts and karma. Some of those issues you are healing may even be from parallel lives or multi dimensional experiences. However one of the biggest things you must face and deal with, along with energies within yourself not coming from the soul, are the negative energies coming from other people and the environment.
