These two Embodiment of the Goddess Activations are the balance for each other. Kali is the destroyer of ego/shadow and the work that she does brings up, transmutes and integrates shadow aspects of your being. She literally moves through your cells slaying fear each time you do this activation and continues to do so for 24-48 hours afterwards. You will probably need a large nap - the first time i gave this to myself after i downloaded the activation i went to bed for a 5 hour nap in the middle of the day. I also found myself stepping into my own power in a much more palpable way. Kali is often misunderstood in popular culture, she is a no-nonsense and very direct being who is also very wise and very loving (you could call it tough love - she will tell you what you need to hear rather than what you want to hear)
Qu'an Yin provides the balance in this pack, as she opens you up to greater levels of love and compassion for yourself and others. She is the wise and loving Goddess who assists us in connecting more deeply with our heart energy and working with it. Her softness is the perfect balance for Kali's take no prisoners approach. It is recommended that you do the Kali activation first and then Qu'an Yin a couple of days later in order to receive the full benefits and understanding of each. And you can go back and do them again at any point where you feel that you need to. Each time you will go a layer deeper.
