The Pink Mulla Mulla is for those who have suffered a deep spiritual wound long ago, often in their first incarnation, where they felt abandoned by Spirit which has led to a deep scar on the soul and psyche. It works on the outer causal bodies clearing sabotage (and fear of spiritual abandonment once more) that is stopping their spiritual growth.
On an emotional level, Pink Mulla Mulla is for those who put out prickles to keep people away.
