As like the ports in your computer that can be open and closed which allow the actions of send and receive , with some things you may be aware of the traffic going in and out and well many things , you possibly aren’t aware of the activity . Good firewalls watch this activity and give alerts . Consciousness , awareness , mindfulness , presentness is your firewall . Don’t let your firewall down . Don’t leave it set on “auto ” . Keep your ports monitored for threats(forced thought/topics/flooding that aren’t yours etc that were acquired into subconscious habit/patterns/traits … ” auto ” ) . Be careful of what you allow incoming , be mindful of what you send outward from your wireless transmitting router ….. Dave Emm . Look In Not Out .
