Obfuscation is the action of making something obscure, unclear, or impossible to understand, so that the person will not see clearly the real motivations behind what is being presented to them.
When people do not have the whole picture of events, and they are being deceived and manipulated with only limited access to the truth contained in circumstances, it obfuscates their ability to make informed, clear and well thought out decisions.
No person can be truly self-determining and make positive choices in their life direction, if they are reliant on people that are lying and deceiving them with false information. This is a critical reason to discern liars and manipulators, and get them out from influencing our life decisions, stop giving them access to our most intimate and vulnerable aspects. All people need to earn our trust by demonstrating trustworthiness. We can unconditionally love people that are deceivers and manipulators, even as some may be biological family members, but we need to become 100% clear that we never allow that person to exert any type of control over us, by setting strong boundaries. It does not matter who they are and what their position in life is, or that they have doctorates and titles, or they are blood relations. If they demonstrate these negative behaviors, if they become abusive when you reveal your true self to them, stay awake and alert, observe everything and be wary of them.
