This is the second attunement of a series.
You need the first attunement to get this one.
The Holy Blue Flame is the first part of the heart of God/Source.  It is one of the flames that ignite your inner connection with God/Source. After this are the following attunements: Holy Golden Flame, Holy Pink Flame. Together they form the heart of God/Source in you. This attunement comes with a general cleanse beforehand, an explanation on what energetic manifestation it stands for and on how to use it.
