The observer does not interfere , but once he/she does,very important data is missed first of all about ones self or pattern .
Once I interfere ,i also lose contact with the moment ,quite simply the small part of me ,takes me back to my old pattern ,the abode I live in ,I realise the small part that is me cant live in the moment ,so I revert back to what I know best .
I also realise that the moment can be expanded upon ,in other words made more visible ,I also know very few people can live in the moment ,their abode is a fleeting one ,so the moment to moment living is non existant ,in other words its more or less invisible ,the small part that is us can't stay with the moment .
A major help her is the observer ,who needs to learn not to be carried away into distractions ,interferance is a distraction from the aim of the observer .
So interferance needs to be brought into a more visible state in our pattern that is our makeup,only the observer can do this .
