The aura - that protective shield of energy surrounding your body - is like Srinagar: it's perpetually under attack from unwanted energy that we tend to absorb 24/7. Extending anywhere between a few inches to several feet, the aura is your psychic shield. Simply put, the aura strengthens your immunity, protects you from unwanted energy and brings you opportunities. Though the magic of the aura and its importance is much much deeper, we will not go into that aspect for now.
Your aura is in a constant state of change. It either increases in size depending on whether you have involved yourself in an energising exercise like sports, singing, laughter, etc., or, it gets drained depending on your mood, health or your interactions with people of lesser energy. When you get a ailment, it actually 'hits' you about 3-6 months before you actually feel the symptoms. That's because it touches the aura first, and that little voice inside you warns you slightly of an impending health trouble. That ailment takes that many months to come to the physical body.
Given this reality, it is a good exercise to "clean" it ie. remove traces of bad energy that may have got 'stuck' to it. There are many ways to cleanse any unwanted energies in your aura. Some of these are physical acts like smudging or showering, while some are visualisations.
When we speak of cleansing the aura, we are not implying that it is "dirty," but one can over time, especially when dealing with other people through the course of a day, pick up bits of their energy and emotions. These may be positive or negative, but they are not yours, and can affect your ability to stay grounded and centered.
In general, an aura-hygiene program should be part of your routine on rising and retiring, just like washing your face or brushing your teeth. This will ensure that your aura doesn't get depleted at any time.
Aura Cleaning Techniques:
* The concept of burning incense in places of worship and also in the house, is to clean the aura. Specific contents in the incense possess the ability to clean auras.
* Water is an excellent resource. Add a little rock salt to the water before bathing. Rock salt has the quality of absorbing negative energy. That is the reason why pilgrims are advised to bathe in the sea before entering a place of worship. A pilgrim with a clean aura has a lesser chance of polluting the energy in that place of worship.
* Visualising golden light or white light flowing down from the heavens and cleaning your aura is also an excellent technique. This comes under the process ' Creative visualisation'* One can cleanse the aura using nothing more elaborate than breath: when breathing out, visualize all your negativity being flushed out, and breath in fresh positive energy.
