Confidentiality
A request for confidentiality, privacy, secrecy - is a request from the ego.
Agreeing to keep something confidential, private, secret - and agreeing with someone that it is important to do so - is actively validating another's ego.
Not agreeing to keep something confidential does not 'mean' that there is an intention to gossip.
There is no such thing as 'private' anyway. When we connect with a person, we sense/know directly their mental and emotional state - it cannot be masked. Attempting to keep things private only demonstrates that there is a desire to keep things private - it demonstrates fear, disconnection, judgement, suffering.
As someone feels less and less fearful, there is more and more openness. Less fear doesn't cause more openness - they happen at the same time, and are the same thing.
At a certain point, there is more openness than fear - and the draw to bring what we think and feel 'out in the open' (despite the 'consequences') is stronger than the draw to 'keep things private'.
When the one who is 'sharing' is met with openness and clarity, over time, the sharing becomes easier and easier, less and less of a 'thing', and the idea that there is anything to fear becomes more and more ridiculous. The concept of self appears to change - from the one who has an experience, to the one who is aware of the experience. Experiences become less and less personal, less and less heavy, and one becomes lighter and freer.
While the ego fears being 'found out', and seeks to avoid this by requesting confidentiality - one's true self fears nothing.
