There are 2 dynamics that all crystals have. First, they all have a resonance or vibration that fashions their colour. The atoms contained within the gem vibrate at a frequency that some parts of the body and its aura are matched to. Second is the way that crystals can harness energies and divine communications. Light can be focussed and refracted through crystals and so can psychic energies including those that can heal. 

Healing

To begin with it is vital that your crystals are properly prepared for use. So that they are attuned to your own body vibrations you need to "charge" up your crystals. You will read that there are many ways to do this but I favour the following methods as they have worked well for me.

• Place your crystal(s) in a dish of water that has rock salt added to it. Make sure the crystal(s) are completely covered and let them soak for at least 24 hours. Once done, if you can place them in direct sunlight to dry naturally but a window sill will also be fine. Then try and hold the crystal in your dominant hand for as long as possible before use to create the link. 
• Place your crystal(s) in direct moonlight during the waxing stage. This is when the moon goes from being new to full. Again a window sill will do the job and once done carry the crystal(s) on your person at all times. This helps strengthens the link between you and builds the link necessary for healing.

Care for your crystals by keeping them in a pouch, preferably silk, or wooden container where they cannot get damaged or chipped. 

Chakras & Prana

Some time ago it was recognised that the body has energy centres and the Indian mystics of the time called these "prana". Prana is the universal principle of energy. It is vital force. It is all pervading. It may be either in a static or dynamic state. It is found in all living things from the gigantic to the tiniest. It exists in the form of a unicellular amoebae to man and from and ant to the elephant. 

"It is Prana that shines in your eyes, Prana that the ears hear, the skin feels, the nose smells, the brain and the intellect do their functions. Fire burns, river flows, wind blows, through Prana. The aircraft moves in the air, train and cars move through Prana. Radio waves travel through Prana. Prana is electron. Prana is force. Prana is magnetism and Prana is electricity." 

Even the sun, moon, the clouds and the very earth we live on are a blessing of Prana. Knowledge is Prana.

The Indian mystics identified seven major chakras, or wheels, that are connected along our central nervous system at various points. Often these points are located at major organs and glands where energies collect before moving on. The chakras are like regulatory bodies where they monitor the amount of energy entering and leaving the body at that point. When working well the energies within us flow through smoothly and uninterrupted and we experience a feeling of balance and well being. However, if there are blockages at any of these points we can feel apathetic, tired and out of sorts. You may even experience pain or depression besides other aches and ailments which may be an indication, and we do stress, an indication that your chakras may need balancing. This is achieved by rebalancing or retuning the body's vibrations by the use of music, scent, colour and the crystals associated with such.
