Crystal
The shape of a crystal may exert a significant influence on its mode of action. 

 Some of the shapes of crystals are natural, and some are man-made.  In each one of its configurations, the basic natural energy of the particular crystals is preserved. 

The uniqueness of the shape lies in the fact that by means of the particular shape, it is possible to program the crystal to receive or transmit energy in various ways, and to dedicate it to various roles. 

When you wish to use a particular crystal of a specific purpose – one of those that will be discussed later – you can choose the configuration or the structure that suits the crystal.  Quartz crystals have their own unique configurations that will be described separately when we discuss the properties of quartz crystals.

The Cluster Shaped Crystal –

A cluster is a natural configuration that consists of a group of crystals.  The formation of the cluster reinforces the power of the crystal, and helps it spread its energies in a stronger and more diverse way.  The crystals in the cluster reinforce, charge, and purify one another.  It is used for purifying other crystals.  For this reason, the quartz cluster is used, in the main.  The citrine cluster is considered to attract abundance and prosperity.  The amethyst cluster is very soothing, and purifies the atmosphere and the air in a room.  Because they are groups of crystals that co-exist and cooperate in perfect harmony, clusters are superb for placing in rooms in which group activity takes place.  The energy of cooperation and unity that they transmit exerts a beneficial influence of groups that work together, on workplaces, on classrooms, and on groups that meet for meditation and spiritual development.  Because of the multiple crystals they contain, the clusters transmit powerful energy and spread harmony wherever they are placed.

The Egg Shaped Crystal –

Many crystals are industrially fashioned into an egg shape.  Using an egg shaped crystal; it is possible to cleanse the aura (by holding the crystal between the thumb and the fingers), locating holes in it and filling them.  Some crystal healing practitioners use egg shaped crystals as an aid in Shiatsu, reflexology, and acupressure treatments, because it is easy to hold (its shape fits in the palm exactly), and it can reinforce the therapeutic energies.  The pointed end of the egg can be pressed into the area being treated, or onto an acupressure or reflex spot.
