For e.g., many a times it’s been noted that people who lose a limb in an accident or other sudden occurrence, continue to feel that they still have that limb. When you view their auric body, you will continue to see faint traces of their limb. Once the physical part is gone, the auric body also diminishes over time and after a while- one will not see the “auric limb” for that amputee.
The other aspect of this auric body is that all kinds of physical ailments and other problems are first noted in the auric body. At this stage they can be dealt with comparative ease than when that problem manifests in the physical body. Most energy workers help people by utilizing, cleansing and other wise positively manipulating the energy of their auric body.
Also several of the alternative healing methods such as Bach Flowers, Reiki etc. work on rectifying issues in the auric body- so they are never manifested in the physical body. In the case, where a physical problem has manifested; working first on the auric body helps to treat the core of that issue and prevent any reoccurrence. Of course the real “core” is in the Causal body, but here we are speaking strictly from natural healing philosophy perspective! ;)
Also energy drains and other psychic level help and attacks happen in the auric body. When we take a shower, along with cleaning our physical body, it also helps to clean and freshen our auric body. This is why people find showers & bath very rejuvenating. In addition, it is a good practice to periodically cleanse the auric body. You can use any of the techniques used in various natural healing modalities or simply use rock salt- you can use it in bath as a cleansing (and relaxing) bathing experience or simply take a little rock salt in your hand and move it over your body. Rock salt has been known to absorb negative energies and helps to give a quick, effective and refreshing auric bath. So next time, you feel all life being sapped out of you from tiredness and stress, do this little rock-salt auric bath and instantly feel vibrant and reinvigorated. Also, wearing Rudraksha cleanses the aura. Part of the reason why ancient Sages wore them.
Now comes the most important and also the most complex body we have- our Causal body. This is our connection with our soul journey. It contains all our karmas and samskars (karmic memory impressions). EVERYTHING that one experiences first finds its source in their causal body. Then if that karma is ripe to be fruition-ed, then it will manifest in the auric body and then finally in the physical body.
When one dies, their physical and auric body perishes BUT their causal body continues. This is the main layer of a Jiv (or Jeev, individual soul). Please note the article on Jivatma. Then, when it is time to manifest again in this physical world, the causal body which exists with the Jeev, then takes on an ego- which then provides the physical body and its associated auric body.
