It is true that mixing with others too closely tends to lower the condition, if they are not themselves in the right attitude and live very much in the vital. In all contacts what you have to do is to remain within, keep a detached attitude and not allow yourself to be troubled by the difficulties that arise in work or the movements of people, but keep yourself the true movement. Do not be caught by the desire to “help” others—do and speak yourself the right thing from the inner poise and leave the help to come to them from the Divine. Nobody can really help—only the Divine Grace.
