HPS Pythia is saying if and ONLY IF you are having problems with enemy attacks or attacks from unaffiliated spirits on the astral, engage yourself in exercise, athletics or sport, social activities, mindless things on TV (comedies, not things like horror, documentaries or anything too 'deep' or disturbing), or things in the real world that deal with pure processing, action or logic. Whatever is bothering you will get bored and go away.
Music (unless you are dancing or something like that), art, video games, daydreaming, aimless thinking and anything too right-brained, visual, psychic or abstract can be an opening when you are experiencing shitheads on the astral. When you understand how things like Neptune and its energies work you will understand this more fully. The advice is just temporary. Not a permanent rule.
Social activities in real life especially are the best way of shutting off and ignoring malignant entities. Plus most entities will not harass two or more humans.
A few people who experience endless attacks tend to not have real life friends.
