COIN

Any coin can be used on the forehead, however silver or copper coins are preferred as they are better conductors of electrical energy. 

The coin attracts the electro-magnetic energy (Prana) in the air around us into our subtle energy centre located at the 3rd eye position (Ajna Chakra). This helps to purify, cleanse, open and energize this energy centre which in turn activates the other 6 energy centres in the body. When these energy centres are activated, purified and open we experience better physical health, mental peace and the innermost Bliss.

Note: If the coin falls during any part of the meditation process, simply leave it there. Don't remove the hand position to place the coin back on the forehead.
