All the fully-enlightened Masters that Charmian has met have Presence.
Once or twice in childhood, again in young adulthood, and increasingly through the years she has felt Presence.
What is it?
During childhood and early adulthood, being brought up a Christian, she would have called it the Holy Spirit.
From her later 20’s she would feel it when reading a book about a spiritual Master. She knew that the Master was communicating with her, encouraging her, letting her know that he / she was there and aware of her desire to connect.
It meant that she could easily distinguish the presence of a Master. This was useful later on.
How do we invoke it?
She knew that in deep meditation she could sometimes feel Presence coming from within herelf, but it was rare.
Then when she met her first Master in the flesh she could feel it within herself day and night for 4 1⁄2 years, transforming her. Sometimes we are given a taste of this to encourage us, sometimes it is permanent.
It feels sometimes as though we can barely speak for the awesome beauty and power of it. In the presence of a Master we are bathed in this energy whether we realise it or not.
As our soul takes us back into itself we enter this state permanently. We have then become a fully-enlightened Master.
