When using these cards in a healing, use them as a tool to help guide your intuition. When we are guided through the healing, this is just another way for the Source to communicate with you. Pull a card before healing and be guided by the symbol.
Some will resonate with you more than the others. Be drawn to the ones you like and use them in everyday life.
In this card deck there is also a double card with a symbol on. This is the Ankahrana. This symbol energises and likes to be visible. Put it in your space to help balance.
There is one card that I would recommend not using in a healing. That is Raku – the master symbol. Although no harm will be caused by using this, it would be respectful if you did not use it unless you yourself are a Reiki Master. Raku can be used in an Oracle reading or in attunements if you feel drawn to do so.
I would also advise not having all of the symbols on display together.
