Openness starts with seeing our own ugliness.
Until we don’t see how deeply attached we are to people, things and our own thoughts, there is no possibility of coming out of it.
This attachment leads to self centeredness which is the ugliness of the mind.
Openness simply means observation of all the attachments and through observation the attachments start reducing.
Open mind is the mind that is least attached and can see reality as it is.
