Presence is the key, the quality that allows change and healing to happen. We can hold Presence to anything. This is also often called ‘holding space’, particularly if we do it to facilitate other people.
Some people are already able to hold Presence/space to themselves, giving themselves a space of non-judgement; others have yet to realise that they can do that, and so believe themselves to be dependent upon external groups or others to provide the base of safety that allows them to touch their Awareness into some things.
One-to-ones or group events may make things easier or quicker, or provide prompts we may have taken longer to get to by ourselves, but ultimately it is incorrect to say they are the source of our power. Just as with Emotional Infinity, holding Presence for ourselves is a natural capacity, and a basic prerequisite for a full and fulfilled life.
