In a couple of weeks I will be attending a retreat which lasts for 21 days. We will be learning to live on light, or some call it 'living on prana'. The first week we won't eat or drink anything, and from then on we get a cup of chai tea and some coconut milk each day, I believe (not sure about the entire program). I've been told we are going to face our fear of death and I suppose that's an interesting exercise of its own. However, some people choose to make it their permanent lifestyle.
Now I am wondering; are there any gnostics who are doing the alchemical work and are 'Living on Light'? Are these disciplines compatible with each other?
Thank you in advance
God Bless
