Awareness is a huge step towards growth and change.
If we are aware of our thoughts, emotions, reactions, feelings, then we are awake and conscious. It means we have realised that we are not any them, that we are the witness of those things.
The true being that we are can only flourish once we realise that we are not those things.
Being aware of our thought, feelings, reactions, and the resulting emotions enables us to be able to change them, to accept them, to stop associating our true self with them.
Inner peace comes when we are aware as it means we are conscious and have transcended the mind.
